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?

thought a 235/40 on front woukd take away any scrub issues

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.

I basically have it down to 3 tyre choices and they are all at the lower spec. Main reason at this stage is I am still sorting / ironing out the car and until it laps consistantly and reliably.
So to that I have it down to:
All tyres are 225/45/17:
Nitto NT01 treadwear 100
Handkook RS3 treadwear 140
Nankang AR-1 treadwear 80
Tyres are between 160-175 a corner which is bloody cheap IMO and I guess that will come with the trade off of overall grip. As stated I was running the older 888R. The new R888R are near twice the price of these bangers.
Anyone had any experience with the above mentioned I would love to know. Appreciate feedback on NT01 vs 888R above, thanks mate.

NT01 is not what you say a true semi, although it's 100 treadwear. However going to say a Hanhook Z221 is like night and day.
Also don't listen to the interwebz saying NT01 uses the same compound as the R888, it's not based on user experience and the characteristics of the tyre.

the z221 is over double in price at moment so not on table until I have the car ironed out.
How does the Rs3 work in your experience though?
