Hi there,

since I´ve changed my stock wheels and tires to the V rims I observed an overall smoother ride quality with this new non run flat tires.

I have on front the 235/45 19 and on back 255/40 19 all "Pirelli P Zero Rosso Assimetrico".

Now I carry 2 cans of tire-pressure- kit in my trunk in case of an flat tire so I really don`t see any problems with this. Here in Germany it`s not allowed to fix a Z or W rated tire anyhow.

Any problems with the larger wheels on the base car? The SLA has to be larger so could be effecting the speedo and ride.

Hi goglobal,
you will have no speedo errors with following wheel/tire combination.

If you use your stock rim you have to get 255/45-18 tires

with 19 inch rims the tire size would be 255/40-19

with 20 inch rims the tire size would be 255/35-20

I have the original XLR V rims on mine with 235/45 - 19 on front and 255/40 - 19
on back and they fit just perfect.

Today I made a 500 mile trip with my new wheels/tires and the car feels now even more better than the already good stock ones was. I think a benefit goes because I have the non-run-flats on, they feel altogether smoother than the run-flats.

Non-runflats

The XLR has a much smoother ride with runflats than the Corvettes without runflats. I ran non-ruflats on my vette, but I always felt a little uneasy traveling in areas where highspeed tires were not available. One experiance I had was that one of my tires on my vette was at 12 lbs when I got into my car in the garage, I had to stop at 4 locations to fill air into the tire to 36 lbs before I reached a tire repair dealer.
