Tire Size help??

:confused:
I have 15 / 75/235 on there now, its a 2wd. I can not find factory 16 or 17s wheels in 5Lug. So I decided to keep the 15s and go for a bigger tire...

I have in mind 15 / 75 / 265 ?? Can someone tell me if that will be a good buy? I want to truck to sit up higher than it currently does! Which is why I think the 75 should do that... Let me know if im wrong.

well just put some 15/75/265 on him, and he sits up alot higher, and looks beefier... I must say, nothing less than 265s now!! WOW :smile: Even rides better.

dont forget to get you PCM updated for the new tire size so you dont screw up your tranny, like I did.

Take a look at this online calculator

my original was 235/75/15 my new ones are 265/75/15

thats LESS than 3mph miss calculation by the computer!! so, I wouldnt worry! It looks 100% better also. It really fills most of the wheel well out, but still has plenty travel room.

Tire size changes can affect the gear ratio, but I think mine was just a "straw that broke the camels back" situation... but I figured itd be worth noting cause you never know.
