I'm strongly leaning towards getting the BBS RS-GT Diamond Black wheels, 18x8.5 front and 18x9.5 rear. I'm thinking about Sport Pilot A/S 245/40/18 front and 275/40/18 in the rear. Please give me your feedback if your running these tire sizes. Thanks!

 

I will let you know after I put mine on. Noticed tires were feathering plus I get that low-speed roar from the front end--going to dealer for alignment, etc. before installing new tires/wheels.

My new stuff (from Discount Tire Direct)--ENKEI RPF1 wheels 18x8.5 front/18x9.5 rear:::FALKEN GR BETA tires 245/40-18 -- 275/40-18

 

I'm installing those very same tires this week. Michelin Pilot Sport A/S (All-Seasons) 245/40 18 front and 275/40 18 rear on the Nismo wheels. Expensive Tires - $250/tire front and $320/tire rear. But from my research they should be great for dry pavement and when the roads get wet and slick.

 

dont have the michelen tires, but do have tires of that size.

run fine, but I think Im going to go to a 255 in front, all other stuff the same.

 

The "perfectly" spec'd tire setup for 8.5"(front) & 9.5"(rear) is:

*245/40/18's on the front

*275/40/18's on the rear

 

I'm running 245/40/18 and 275/40/18 on my Nismos. I have Dunlop SP9000s. Great tire/wheel combo. Great Handling tire. Absolutly no issues.

perfect setup in regaurds to diameter.

but I think the 275 looks better fit on the rim, where to me the 245 have a tiny inward slant to the sidewall as if they could be 10mm thicker. not just to have, a wider front would help to reduce understeer, which a 30mm difference front to back only makes worse than the 20mm difference it had stock.

 

The tires as I listed above are now installed. There is a noticeable increase in traction. The look from the rear is awesome, with those wide tires--kinda like a Porsche 911. In both the front and rear, the tires seem to fill out the remaining space in the wheel wells. Not sure I'd try to fit anything larger.

 

Thanks for passing on the info.

 

i have Goodyear F1 GS-D3 on my nismo and just love them.
tread wearing, wet track, grabbing.. i just love them.
