Hey guys Just woundering how much power do you lose every time you go up a inch in your tyre size while using standard diff gears

Varies from car to car.

I went to 33 from 31 on my GQ Diesel Auto, and it sucks the big 1..

Others go from 31 - 35 before suffering...


All depends on how happy you are to lose a little power.

IMO, if you go to 35's go 4.6 diff centers.

yea i plan to get diff 4.6 i heard some where that you lose 10% for every inch could this be true it seems like alot

On my old 2.8 D hilux I put 235/85R16's on it (up fm 205R16), which is about 2" increase and it sucked big time. Couldn't pull the panties off a hooker, and hurtled down steep hills. You can put up with it but it definately doesn't feel normal.
