BJ40 and R15 33"x12.5 Tyres (1 Viewer)

Hi,
I haven't been here in a long time
I put on larger wheels R15 33 "x12.5 ET-40 and the machine became difficult to control on the road. I constantly need to hold the steering wheel firmly and catch the trajectory.
How do you deal with this problem? What improvements should be made?
The steering wheel does not have an amplifier.

Sounds like a caster problem. Maybe need some shims?
What size did you have before, suspension setup do you have?

Oh yeah, I completely forgot that there may be a problem with the caster, will need to check, thank you.
Before that 31 ′ ′ narrow standard, it was 100km / h tolerably

Actually the road feel has been amplified by the larger tires, more rubber on the road. This can be made worse do to worn tie rod ends or improper alignment. My FJ-40 runs the same size tires and didn't alway have power steering and actually had a smaller than stock steering wheel. Double check your toe in setting, I run 1/8" toe in which seems to keep things in check.

Either shims or step down to a smaller tire, either in diameter or width.
33*10.5*15 is a better fit for a 40 series.
A smaller tire is easier to get going, slow down, and steer.
