Pat, good day. Found this online, sounds rational but I can’t confirm… —— The equivalent size to the GR70-15 would be P225/70R15 - almost identical in O.D. but slightly wider O.W. than the 'G'(0.3"). The best match in 60 series would be the P265/60R15 - approx. 0.1" taller in O.D., but about 1.7" wider. You may want to check your wheels, though, the minimum width for the P265 is 7.5". The minimum for the P225 is 6.0". While you are at it, make sure the wheels are radial approved - some early cars with bias tires at OE are not —— 1 Link to comment Share on other sites More sharing options...
Riviera Russ 65 Posted April 19, 2023 Share Posted April 19, 2023 I picked up Cooper 235/75/15’s last year from Trail Tire here in Sherwood Park where I live. Approx. $200 a piece. They were in stock in their warehouse. No issues so far. 1 Link to comment Share on other sites More sharing options...
Bloo Posted April 19, 2023 Share Posted April 19, 2023 1 hour ago, Pat Curran said: Not trying to hijack the thread but can anyone tell me what GR70/15 translates into today’s equivalent sizes? Thanks! On the letter size tires, the height stays constant (more or less), rather that the section width. So, a G78, G70 and G60 would all be close to the same height, but radically different widths. This is in contrast to old number sizes as well as newer metric width sizes, where 225/70, 225/78, and 225/60 have more or less the same section width, but radically different heights. All you need to do to get the closest modern equivalent to a letter series tire is to choose the same aspect ratio (70 for a GR70-15), and then pick the tire size closest in height. From @MikeJS' post, I gather that is P225/70R15. 1 Link to comment Share on other sites More sharing options...

EmTee Posted April 20, 2023 Share Posted April 20, 2023 If you have any doubt about your old tires on the highway (as in the trip to Spokane) bring your IR thermometer with you. Drive 50 miles and stop for a reading. Do the same at 150. If all is good and there is no bumping or vibration, then just shoot them whenever you stop (i.e., for fuel or food). If the pressures are correct they should run fairly cool. If a belt shifts or some other structural issue arises, it should be felt either in the steering wheel (front) or seat of the pants (rear) before failure occurs... 1 Link to comment Share on other sites More sharing options...

Russ, if you delve into it today, you'll find there's absolutely ZERO stock and most listings have been dropped. That is through normal tire shop and online channels. Then there are the fly-by-night small time dealers with huge mark-ups. Nothing in-between. But, stay tuned. I have a lead to follow-up on! 10 hours ago, EmTee said: bring your IR thermometer with you. They are so cheap, I keep one in my Riv. Thanks for the advise though. It wouldn't have occurred to me to pull it out of the glovebox for tire monitoring. Again, THANKS!😊 Always hearing issues on over heating of something or another. Never have that problem here.

Riviera63 Posted April 20, 2023 Share Posted April 20, 2023 I have been in contact with John B. aka XframeFX and offered him the 4 Hankooks (225/75) I will be taking off of my car for $150 for the 4. They are less than 2 years old and have less than 1500 miles on them. He found that shipping of the tires to him where he was prohibitive but, he has informed me that he was able to score some whitewalls. The offer I made to him stands for anyone else in Canada that needs whitewalls and isn't able to get them. If you can figure out a way to get them from me to you. They are yours. If you know of anyone in that situation, pass the word. Bill 2 2 Link to comment Share on other sites More sharing options...

RivNut Posted April 21, 2023 Share Posted April 21, 2023 There are many reputable shops around here that sell new tires as well as used tires that have been inspected for age and wear.

No online robbery for price, no shipping, no protection fees, no PST, no BS! Good Ole Edmonton! WSW for Suretrac Whitewall Power Touring is a little wider, 1.4" for 70s and 1.5" for 75s So, now wouldn't mind feedback whether to stay with 225/75-15s, or since tire places have been shoving "trailer tire size" down my throat, switch to 225/70-15s with a 1.4" WSW, A perfect size would be 235/70-15 as commented by Wayne R but no such thing in WSW today.

XframeFX Posted April 24, 2023 Share Posted April 24, 2023 Those 225/70-15s, should've had them put on hold. They were gone when I arrived. Thought he told me they had lots and they do but in 215/75-15s. So I placed a deposit for a set of five 225/70-15s @ $127 CAD to arrive late June! For size 235/70-15, hard to find and claims a 3/4" WSW stripe but appears wider in the image - Vitour Galaxy R1. Must be for another market as it's not all season. I like the tread design.

Communication breakdown, somewhere. When I went in on Saturday near noon, Dimetri was with another customer, but he knew right away that it was you he was talking to, and said ya, they have a least four of the size you called about, but the 225-75-15 that I was looking for would be in by May. That's when I texted you. Did they say that they just sold em? If so, it wasn't me that bought em', most likely it was simply too many different sizes being talked about (has my head spinning...) and as mentioned maybe just a communication breakdown. Good news I guess, they seemed pretty confident that they will have the stock when it arrives in May/June. Not sure if I'm real crazy about the wider whitewalls these have, but I'd rather have something relatively new (and cost effective) than having to go to black walls...

65VerdeGS Posted April 25, 2023 Share Posted April 25, 2023 Hi John and Mike, Not wanting to rain on your parade. Do these Vitour tires suffer from the dreaded 'brownwall' syndrome being complained about so much on the old car forums these days? You might want to get some assurance from the tire dealer that you can return the tires if the whitewalls go brown. Just a thought. Link to comment Share on other sites More sharing options...

Unless low profile, all non specialty tires up here are all season. Performance Plus Tire in San Diego appears to have 235/70s that only Vitour has in WSW spec'd at 3/4". The image seems to be more of a 1.5" WSW. There was some reference to Germany when researching Vitour. Doesn't figure because they are priced low ($130 USD/tire) Mike and I are chasing SureTrac rubber, from Asia, probably China. That and along with a wider than desired WSW in all season no too cool but, at $127 CAD/tire and available locally, a lot better than BSW! As for brown showing through, yeah, wouldn't surprise me. But they won't be at purchase time, I'll inspect them before the install. Can't do that with an online purchase. 1 Link to comment Share on other sites More sharing options...

Cost spread over 7-8 years makes me feel better as does the anticipation of whitewalls that actually stay white. I ordered 225/75's with a 3/4" whitewall. The whitewall width on my current Hankook's is 5/8" and so is my Nexen spare. I realize that the whitewall of the day may have been wider. I prefer the narrower whitewall just as I prefer the larger tires. In my opinion the cars of that era were "under tired" and look better with wider and larger tires as compared to the tires of the day. The shipping was less than they had estimated when I first called and they said 2 1/2 weeks to my door. Bill Bill, I found the 7.10 R 15 ww one inch wide attractive. I just happen to like the radial bias look. Telling the truth, the modern radial tire seems to give me a better ride than the 7.10 R 15.

MikeJS Posted April 28, 2023 Share Posted April 28, 2023 Good day For what it's worth, my vintage '90's whitewalls are Kelly Springfield 225-75-R15 tires, I've never had any issues with browning, and when I do clean them, I usually also use a SOS pad. Always worked great. Something I don't do often is read my tires. Interestingly enough, and I'm not sure how common this is but embossed on the tires is the following warning... "SAFETY WARNING - Serious injury may result from... Explosion of Tire/Rim assembly due to improper mounting... Only specially trained persons should mount tires" Something I may have read years ago, but again, how often does one read their tires... *goes out to read the rubber on the wife's Honda* Later, 1 Link to comment Share on other sites More sharing options...
Riviera63 Posted May 1, 2023 Share Posted May 1, 2023 Received my Diamondback tires today. I ordered them late on a Friday afternoon. 2 weeks and 3 days later they were on my doorstep. I am very impressed with their service. I cleaned one of the whitewalls off. The whitewall was exactly the width I specified and the whitewall is thick and sturdy. How nice it is to look at a whitewall that is actually all white. They do specify NOT to use bleach on the whitewall. Simple Green or 409 is their recommendation. I can't wait to get them on. However, Mother Nature is not cooperating. We are at 42 degrees right now with wind. Hopefully, the weather will improve so that I can get the car out of hibernation this weekend.

The SureTracs I have coming also come with blue protectant. 2 hours ago, Riviera63 said: Hopefully, the weather will improve so that I can get the car out of hibernation this weekend. When having them mounted, I always know but sometimes forget to add to the Work Order. That is "stick-on" balance weights, no clip-ons for alloy wheels! Although my latest Driver Cars only accept "stick-ons". For the Riviera, longer valve stems in case I choose to snap my wire hubcaps over rough Formula-V wheels. 25⁰C and sunny here in Edmonton at the moment! Also during tire mounting appointment, I want to look at what series of Formula-V wheels they are before mounting new tires. #802s? Also a good time to measure rim width for regular steel wheels. I'm sure all Formula-V wheels are 6" Since my Asian Tires are so cheap, and I've decided to change to 225/70-15s, I ordered 5. My spare Formula-V wheels with old radials have those nasty 2.75" register rings. Balancing vertically on a railroad tie and beating with a Sledge Hammer and HD chisel, hardly a dent! Heavy Gauge Ring with 5 solid welds! The wheels on my '63 still has register rings but, they seem to be pushed in enough to clear all four 3.5" hubs.

The store called me with 5 mins of order placement and confirmed my pickup time of 8:45am on Saturday. Drove over and the store refunded the install and disposal fees as this was pickup only. They bagged them and loaded in the grocery getter for me. I declared the purchase at customs on the way back and paid the glorious 12% tax and I was on my way.
