I'm getting closer to purchase time on a set of the SEMA-spec wheels for my Z (my house looks as if it will be ready to close in a few weeks; hopefully early March) and had a question or two (maybe three ).

My main question for you is this: I noticed on those wheels you guys ran a 30 aspect ratio tire with the Eibach suspension kit. What I was wondering is, will a 35 aspect ratio tire fit on the same wheels on a stock Z without the lowered suspension (stock suspension)?

Due to the sometimes horrible condition of the roads around here (I live in the country pretty much) I thought that maybe the extra bit of rubber between the ground and the rim might be a good thing.

Will it be a big enough difference to even matter (in tire sidewall height)? Or should I just stick with the 30's.

Also, would it possibly be better for me to do 18's instead and do 40 aspect ratio's w/ the suspension drop (I'm guessing it would fit) for better rim protection?

Hell, I don't even know if 295/35/R19 tires exist.

It's not really a money or appearence thing (although I do prefer the look of the 19's), I just want to make sure that I get the best wheels for my car and that my investment is avidly protected from the unforseen bumps in the road (although I know the roads really well; you memorize them when you ride a sportbike). This is also going to be my daily driver (when I'm not riding aformentioned bike).

Also, I was planning on purchasing the Pirelli Rosso's, any feedback on those?

Thanks a million for all your help with wheel questions on this forum. It is greatly appreciated.

 

Sorry to *bump*. Just want to make sure he sees/reads this.

 

The 35 series tires are actually a great choice in 19"- to be honest, the 275/30-19 + 295/30-19 sizes we used are a bit shorter than the OE tires. A 275/35-19 + 295/35-19 would definitely work (even lowered). HRE is very friendly with Pirelli, and I wanted to use the new Rosso tire- plus I like the look of the 30 series front & back. BTW, the Rosso is a great tire!

As soon as I get in the office tomorrow, I'll check the overall tire diameters of the 275/35-19 and 295/35-19, and report back on this thread. I'll also check & see if Pirelli makes a 295/35-19 and 275/35-19. I think Yokohama offer the 35 front/rear in the AVS Sport. Check back here tomorrow for answers!

Bob

 

the wholesale Tirerack catalog I have shows the Pirelli Asim in a 285/35/19 BUT no tires in the 275/35 or 295/35. maybe they make them, BUT aren't listed in htis catalog

 

Awesome! Thank you so much for all of your efforts.

 

 

The news is not good... I can only find the 275/35-19 in the Dunlop Sport Sp9000 & Bridgestone S-03 and the 295/35-19 in the Michelin Pilot Sport & Yokohama AVS Sport.

A few guys are doing 255/35-19 + 275/35-19 Toyo T1-S: that might be about all you can do in a 'tall' 19" set-up...

I'd wait for the new Pirelli Rosso 305/30-19, stuff it on a 19x11 rear (with rolled fenders)

Well I really don't want to modify the body at all.

I'm sure no one makes 40/19's anyway. Not even sure those would fit if they did hehe.

In this respect 18/35's make more sense just to have a little more tire protection, but I like the look of the 19's more. Hrrm... tough decision.

Thanks for all your help.

 

Geez,

I didn't want the 18"s on my Performance model simply because I didn't want the added expense of 18" tires.
You guys talking about 19" rubber makes me cringe!

 

Want to cringe? You should price the 20x9 (2.5" lip) and 20x10.5 (3.5" lip) HRE 845R I am building for my Lexus SC400...

 

Bob,

Would 295/40/R19 rear and 275/40/R19 fronts fit on the SEMA spec wheels with stock body work?

Pirelli offers both of those in the Rosso.

Thanks!

I'd say there's a chance they'll physically bolt onto the car, but they are really tall.

225/45-18 = 25.97"
275/40-19 = 27.66" (1.69" taller than 18" OE)

245/45-18 = 26.68"
295/40-19 = 28.29" (1.61" taller than OE)

The TCS & ABS systems will be happy, but they are tall enough that the front tires might foul the upper ball joint nut (above the tire).

I can't imagine they would look good on the car (what we call "buffalo tires"), and the gearing will be affected significantly.

I wouldn't do it, personally.

Nuff said.

295/30/R19 and 275/30/R19 it is.
