Anyone nearby want a set of 360 rims+rubber?

Pirelli P Zero
Front 215 45 ZR 18
Rear 275 40 ZR 18

The tires state a maximum pressure of 51 psi. The tire pressures currently are 36-38 pounds. I will get a recommendation from the tire shop when I take the car back in to confirm that the tires are balanced, and the lug bolts are torqued properly.

 

there is the same ad on ebay now (see ebay Item number: 7907700736)
for the modena style wheels with bridgestone tires which I would like to buy for my 83 Mondial isntead of replacing the expensive Michelins trx tires.. It seems from this thread that these wheels will fit a Mondial without modification except perhaps longer lug nuts? can anyone verify before I buy?thanks,
Wayne

 

Email the seller and ask where you can buy 360 bolts from. Then contact that source and confirm for yourself before you bid that you can get the longer bolts. If they are not Ferrari bolts, you have to satisfy yourself that the non-stock bolts will be safe. BTW, I have since found out on hard turns the rears rub and slightly slice up the sidewall at the edge near the radius of the tread. So they look wonderful, but not sure if they will work on the track or hard cornering. Does anybody know if the 355 rear tires aren't as wide? The 360 rear tires are 11 inches wide.

 

Is that why the 355 wheels need spacers when installed on the Mondial's?

 

The 360 rims on the Mondial sure look sharp. I didn't think I'd like it, but seeing the pics, it looks good.

 

Just drove the Mondial again last night, and I am noticing the rear tires rubbing more on corners. Could be that the 360's are just too wide for the Mondial wheel well.

 

Yes, the 250/40-18 would be shorter. Although when placed side by side, the 275 P Zeros are already of a slightly smaller overall diameter than the stock metrics. I remember this because I wanted to know if the new wheels would exacerbate the existing speedo inaccuracy problem. Once I completely shred the P Zeros I will need new tires anyway. Does Pirelli make a 250? What about a 250/35-18, if one exists?

 

Which would be the smallest profile to prevent the sidewall rubbing? There are a number of speed rated tires in the 255/35-18 size. Just go to tirerack.com and search by size and speed rating.

 

Do you mean 255-40 to 245-45? I'm not sure on all the ratio relationships. Have you posted a thread that explains it all?

The slices are at the sidewall near the tread, not the tread. But I will get out there and try to replicate what you suggest, to find out exactly what the problem is.

 

Thanks for the education. From the slices on the sidewall, it looks like the problem is width. So moving to a 255/40 would reduce the width in relation to the part on the fender that it is rubbing by 10mm (half the 20mm difference), plus reduce the height by 8mm (distance from the centerline of the hub)

 

You need longer lugnuts, just bought a set. There is a thread with the pics of the car.

 

In May I broke down and replaced the 275/40's with 255/40 PZero's. They work just great. No rubbing at all even with 4 passengers. I had a little rubbing problem on the left front tire on hard right turns, but I just bent the louvers in the wheel well a little bit and it took care of the problem. Thanks for everyone's help. If anyone has questions about this conversion, I would be happy to help in any way.

 

It looks like the old photos I posted are no longer on Ferrarichat. I'll post them again in case anyone is interested. These are the old photos with the 275/40 ZR-18 Pzero's in the rear. The new tires are 255/40-ZR-18's, but they look substantially the same.
