Cheers guys, Looks like the new A048's will be best option. I'll check out a few places and see what kind of prices I can get. I was looking at the AR-1's as well but they don't sell them in a staggered size which is annoying. That Toyo article is an interesting read what kind of cold and hot pressure do you guys use for Z? Standard weight is 35psi all round but with a bit of weight out of it 32psi front and 30psi be about right? Suppose tread wear and grip go hand in hand but would you be able to drive to the Ring (2000 miles for me) on these A048's or even the R888R's?

Looking for advice on track day tire sizing for standard-ish 350z and what tyres(sizes/compounds) actually effects the turn-in, mid corner and exit speed. I have standard 18" rays and I will be looking to purchase second set to run some aggressive track day only tyres. These are the two possible solutions, Standard wheels:- F- 18x8" (204mm width) R- 18x8.5" (216mm width) Yokohama AD08R's Front 235/40/18 (231mm tread width) Rear 255/40/18 (249mm tread width) This combo will allow a slightly wider width and being track tires the sidewall flex should be minimised whilst maintaining large contact patch tyrerack site puts tread width as per above sizes leaving a 13.5mm bulge on front each side and 16.5 mm bulge on rear each side Second possible combo:- Toyo R888R Front 225/40/18 (208mm tread width) Rear 245/40/18 (226mm tread width) Widths from tyre rack above give 2mm bulge on front and 5mm bulge on rear. From My limited knowledge of tyres it sounds like for racing purposes the tread width should be slightly less than rim width thus allowing preload on the sidewalk hopefully minimising flex. Ive tried to rid the car of as much weight as possible, maybe 80/90kgs for now albeit mostly in the boot but with standard tyre sizes the tyres overheat fairly fast. I've chosen the wider tyre sizes to hopefully reduce this overheating. So the question is, will the increase in width create terrible sidewall flex and the smaller R888R's be better or will they maintain ridgidity and combat the overheating? All solutions welcome
