Gotta get some tires!

[YYCWilliam]

So I’m going to have to get some tires here in the spring...I have a mismatched set on my truck (it was like that when I bought it) stock size on the front(235/75/15) and the rear 31x10.5 super weird I know so I want to get something bigger than the stock size but also not gigantic like the rear. My truck is a 1980 Sierra classic suburban 2wd.

30X9.50 15? There must be a metric size close to that, but don't have time to look it up at the moment.

My c10 had 31x10.5x15 all the way around. Right now it has 31s in front and 265/75/16s in the back. I put new tires on the back of my s10 today, 31s on the back and 215/75/15 up front.

Is that what your running on your truck?

30x9.50-15 is the same height as 235/75/15

Nothing wrong with 31s...

Nope, but if the OP has OE wheels, 10.5” wide tires aren’t ideal due to their width.
They sure look sweet on those 8” wheels though!

Some of the factory rallies were 8” wide. Our burb has 15x8 rallies. One of our parts pickups had the narrower rallies that look like they are 7”
