What Tire Size Are You Running? Options for 360 Rims...

Hi Everyone. I am happy to be back in the Ferrari game and picked up a new to me 1985 Mondial Cabriolet QV in pretty nice shape, black exterior and uncommon red interior. I am quite excited for this thing! It has 360 Modena rims on it (stock ones were not included), I like them very much, and plan to continue using them. They have the stock 360 tires on them, seem to fit very well in the wheel well, no rubbing, no issues with the lug bolts, etc.

My biggest concern is the stock 360 tire size diameters (215/45/18 = 25.6", 275/40/18 = 26.7") are way off from the stock Mondial tire size diameter of 24.9". It looks like alternative tires size of 225/40/18 (25.1" diameter) and 265/35/18 (25.3" diameter) are much closer to the stock diameter. I am concerned the larger size stock 360 tires will negatively impact the driving experience such as impacting acceleration, handling, and the speedo accuracy, but am also concerned that if I go with smaller diameter tires the wheel gap will be even larger than it already is! It looks like there are quite a few great and reasonable options for doing a size of 225/40/18 and 265/35/18. Before purchasing a set in that size, I wanted to check in and see others thoughts and if I am missing something. Also, are there any suggestions for reasonable cost options for lowering the suspension just a bit (the wheel gap, in the front at least, seems large and I am concerned with going with the smaller diameter tires there will be even more wheel gap).

Regards,
Shane

Stasha, I agree that the 360 wheels look quite nice on the Mondial QV. They do not stand out as too modern. Such a five spoke basic design is timeless enough I think. Normally I wouldn't want so much gap to see such small and basic brakes but the rims really do aid in the presentation of the car and make it feel more "fresh" whereas the original rims might make it feel more vintage.

Gunn, thanks for the comments and links. Are you running 8.5" rims all around thus 225 at the back too? 245 is wide at the front from what I have seen others use. The 360 rims I am using are 7.5" wide at the front and 9.5" wide at the rear. Per the attached table 225mm front and 265mm rear tire widths are appropriate for the 360 rims. Share a picture if you don't mind of your set up. You are happy with how it rides and feels?

Gunn, thanks for sharing and for the info.

Theunissenguido, yes, the spare tire is in the boot.

 

Pretty car and excellent looking set up. I like the staggered look too. I bought tires... ended up going with the 225/40/18 and 265/35/18 Hankook Ventus Evo which it looks like you are running too. What size tire are you using? Do you have anything done suspension wise? You look to have less wheel gap than mine. I won't know how it rides for a few months until the snow here in Wisconsin goes away.
