Largest Tire Size I Can Add with a Lift

[Trail Brian]

In the “old” days the trucks came with really small tires and transmissions with
2-3 or 4 gears. Adding big tires really affected the ratios.
Going from 32” to 35” tires ( about 8% increase in circumference) on a truck with plenty of HP / TQ and 10 gears, shouldn’t be a problem.

I agree... might be a bit sluggish from before but to overheat a transmission ? i'm sticking with 35's for that very reason... 37's might be pushing it a bit
