I currently have 225/45/17 front and 235/45/17 rear Toyo 888R's.
I have been told Nitto NT01's are pretty similar (made by Toyo) and have a 100TW. I want to give em a go (unless something else pops up) but they come in either 225/45 (and I dont want to take tyre away) or 235/40 and 245/40 widths.
I run a 17x8 Lenso D1 rim.
From my calcs the 235/40 should be fine and the reduction (albeit sweet FA) in rolling diameter will only assist acceleration.
Has anyone played with this at all and any experiences I can learn from?
Car is 100% track only.

when you step it up to the hankook z221 or the advan ao50 the grip level is on another level.
as for tyre sizing find a combination dont wont rub or limit your castor settings/alignment. 225 is a little on the skinny side and is an unpopular size for semis.

Would a 235/40/17 work on a 17*8 or even a 245/40?
I think the 235s should be able to somehow go on the front of it witjout too much drama?

sidewalls are flush with the face of the wheel.

castor plays a big part too as it moves the wheel further forward, closer to the guards.

If a 235 road tyre is scrubbing going to a 235 semi will scrub even more due to the thicker side walls.

I guess is using a 235/40 over a 225/45 actually going to achieve anything really.
