Technically, yes but I wouldn't recommend anything wider than a 10.50 on a 7" wide wheel.

I think Logan has 12.5 tires on his stock rims. It's probably not the best idea though.

I wouldn't feel safe with 12.5" tires on 7" rims.

Here is Logan: https://blazerforum.com/forum/members/logan-8704/



I looked up what size tires he had on his truck and it looks like they're 33x14"!!! And they fit on the stock rims, so 12.5" certainly will. It's just a matter of how safe they are...not sure they would be.

While they may fit, 7" is not wide enough to safely support 12.5" tires let alone 14" tires regardless of what others may have done. The sidewalls are not meant to bend in that much and can lead to premature and sometimes catastrophic failure of the tire.

The general rule is to not go 4" over the rim width. So 7" wide rim an safely support an 11" wide tire. For a 12.5" wide tire, you would want an 8.5" to 9" wide rim.

i think they rub the frame. i tried it years ago for a spare and for some reason remember not being able to use them in the front for whatever reason

i mounted a 14wide on a 7inch rim before and yeah you bend the hell out of the sidewall. i was surprised the thing even seated on the rim. unless its just a beater offroad truck i wouldnt recommend it

Any quality tire shop won't put it on there.
