I'm not positive as they are out at a shop getting mounted up right now but I think I got 235/40-18's on front and 295/30-18's on rear. I'm mounting them on Challenge wheels. I like the slightly larger rears because the car is a little prone to oversteer. I'll let you know how they fit after I get em mounted. I'm doing a track day Nov 7th so I can give you a track report after that. | ||

I'll state it more strongly... if the actual diameters (which can vary from the diameters computed from the NNN/MM numbers) are 0.1 inch smaller on rear than front, then you will see traction control kick in at strange times. The solution is easy... reach over and flip it off... but if you don't like that, then I suggest different tires. | ||

Robert - >>225/40 18's front and 285/35 18's back are available<< Actually the rears are 285/30, not 35, which puts the diameter 0.1 in smaller than the front. I don't see that as a major problem, but as Brian has pointed out there may be ASR implications. | ||

Robert, what are the actual diameters? (You can find them on Tirerack's site or maybe Pirelli's site.) Just eyeballing the numbers, those seem like good sizes. | ||

John B, what sizes did you order? I also was thinking of getting a set of PZero corsas and using them on the stock Modena rims. I see that 225/40 18's front and 285/35 18's back are available and would seem to be the closest to the original sizes of 215/45 18 front and 275/40 rear. Is this what you ordered? Anyone else try this or have any advice? Brian, what do you think? | ||

Hey, keep us posted on the Corsas. I'm debating whether to go with that tire or the Pilot Sport Cup. | ||

I just orederd a set of Pirelli P-Zero Corsas. They are soft compound DOT legal tires. They are standard on the Stradale. I track my car fairly often so I'm willing to try the soft compounds. | ||

Drewh: Go with S03s in 225/40ZR18 front and 275/40ZR18 in the rear. I run this setup and on my F355 its better than either the S02PPs or the S02s (especially when any weather is present). The 275/40s are 0.1" taller than 265/40s but this is smaller than the amount of tread on these tires anyway. Spedo error can be ignored, and slightly less oversteer is inherent. I can run the same pressure F/R with perfect street and track balance (except MSR). | ||

What is "ASR"? DrewH | ||
| Brian Kennedy (Kennedy)
Member Username: Kennedy Post Number: 491 Registered: 3-2002 |
The thing to watch is the diameters... make sure the rear diameter is bigger than the front diameter by at least a little bit. OR be prepared to turn off your ASR for good. Further, you don't really want to stray from the stock diameters too much, as you are effectively altering the suspension geometry. However, with that said, my 360 on much smaller diameter tires handles AWESOME! | ||

I am looking at buying new tires for my 1999 355 Spider. It came with Bridgestone Expedias (S-01) 225/40ZR18 on 8.0 inch rims front and 265/40ZR18 on 9.5 inch rims rear. I checked out other tire manufactures (ie. Goodyear/Dunlop etc..) and most don't seem to make matching tires in this exact size. I then noticed that the 360 sometimes comes with Bridgestone Potenzas (S-02)with 275's on the rear with the same size rim (9.5 inch). Since the Potenza is newer and supposed to be a better tire (It is now used on the 360 instead of the Expedias) does anybody know if it would be OK or better to change my tires to Potenzas. As they don't make a (265/40ZR18 Potenza) the front would be 225's as they say you need a wider rim to go wider on the front and the rear would be 275 on a 9.5 inch rim instead of a 265 on a 9.5 inch rim. Any thoughts on Pros and Cons would be appreciated. Drew | ||

They are available in 225/40-18 and 285/30-18 which would fit...very pricey, though: $243 and $342. | ||

Is it possible to use the PZero Corsa on the Modena? So far, it does not appear that they are available in standard sizes. | ||

Interesting. I thought the PZeroes were horrid... Pole Positions were a major improvement. I've had two sets of Pirelli tires... hated them both... poor in the dry, worse in the wet, and poor treadwear... of course, given the first two, I was happy they didn't last long. I can't imagine going to the track on them! Wait, are you talking about the normal Pzeroes or the Pzero Corsa?? | ||

I have tracked my 360 with the Pirelli P Zeros and they handle fantastically well. You will never get near their limits on the street unless you are insane. I have tried the Michelins, no comparison. I also ran the Potenza, and the Pirrelis are better. | ||

The factory installed tires on the 360 are excellent to very good in terms of maximum dry performance. Some are not as great in performance but are more comfortable and last a bit longer. My opinion is the following starting with the best performer: 1- Goodyear Eagle F1 Fiorano 2- Bridgestone Potenza S-02A 3- Pirelli PZero Asimmetrico (yellow) 4- Michelin Pilot Sport The differences between 1 and 4 are substantial. | ||

Hi Paul, My Cars shod with Michelin Pilot Sports...mmmmm not sure im happy with them. They have a tendancy to follow contours of the road and are not a good ride.....any thoughts?? Joe | ||

Before I bought my 360 I test drove several. I was amazed at how each one seemed to handle and ride so differently. The first one I drove, which has P Zero's, is what made me initially fall in love with the car, as the handling and ride was incredible. Then, I drove 2 others and the handling was not nearly the same as the first, it just didn't feel as good. I noted both of those had non-Pirelli rubber on them. I don't know if that was the entire reason for the difference, but it seemed logical. My current 360 has Pirelli and it feels identical to the first 360 I drove as far as handling and ride goes. When I say the ride and handling is "so different" between the few I test drove, I mean the subtleties of the ride are very different as far as how road imperfections are absorbed among other things. The P Zero's just seemed to smooth out a rough road really well and seemed to give you that "riding on rails" feeling the best. -- Michael | ||

Gary, You can specify which tires you want in your order. The only drawback is that if the factory doesn't happen to have those tires on hand when your car is assembled, it'll just sit there til they get some. There's no telling how long that could take! fwiw, I ordered P Zeroes with mine and there was no additional delay. | ||

It doesnt take a lot to notice changes in handling characteristics from different tires, especially in the rain. I can definitely feel the difference, although I must admit that most of the feeling is probably from switching from old tires to new ones... Ernesto | ||

I agree with Jim that in most sane street driving there is very little difference among the lot, but even an occasional track event would show up some pretty big variances. | ||

Do you guys really drive your car hard enough on the streets to notice a difference? I can see if you are tracking it, but daily driver seems it wouldn't matter. | ||

I'm awaiting delivery of a new 360. I've noticed that they seem to come from the factory with several different tire brands, including Pirelli PZero, Michelin Pilot Sport, and Bridgestone S-02. What is the tire of choice among the group? Does the dealer have any say in what tires are fitted to the car from the factory? |
