1949 Chev 3/4 ton tire size??

[bifda]

I have just bought a 1949 Chev 3/4 ton truck, what would the original tire size be? At present it is sat on 7.00 x 15 tires but are they correct? Before I buy a new set I want to make sure I get the right size.

Also would you go for white walls or plain black??

Any opinion appreciated..

6:00x 15 according to krause publication, "standard catalog of the american truck".

Thanks for the information. I have just spoken to a friend who has a 1948 GMC 3/4 ton pickup his sits on 7.00 x 17 tires. Is his also correct. Or has someone changed his at some point or were these larger wheels/tires an option?

thanks

I'd go for black wall tires as they would be correct for the time/year for even a 1/2 ton pickup. I think there was only one pickup model that ever had wide whites as standard equipment and that would have been the late 1950s Chevy Cameo.

The 3600 model (3/4 ton) base used a 15" 6 ply. RPO option 280 used 15" 8 ply, RPO option 277 used 7.00-17 6 ply, RPO option 278 used 7.00-17 8 ply, & RPO option 272 used 7.50-17 8 ply. Per Chevy 1949 Specs (page 96). Tires wre furnished by U.S., Goodrich, and Firestone.

Thanks for the reply stude1946, so it sounds like mine is correct on 15" wheels can you please just confirm the size, is it correct on 6.50, 6.70, 7.00 or should it be some other size x 15

Thanks

Also probably a silly question but in your reply what does RPO stand for??

Thanks

RPO stands for Regular Production Option.

Here is a current list.

6.70 size tires were used on passenger cars not on pickups until later in the mid-50's. At the time of your truck sizes would have been 6.00, 6.50, 7.00 and 7.50.

Sorry about not getting back to you sooner. I've been running around looking to prchase a house. The 3600 base was a 6.70x15 6 ply. Options included the 6.70x15 8 ply, 7.00x17 6 ply, 7.00x17 8 ply, and 7.50x17 8 ply which were covered under several RPO (regular production options). This info is from the 1949 Chevy specs pages 96 and 100. Hope this helps.
