Mine are not rolled. It is #4460. 9/72 build date. '73L model.



I have the 15" Campis 8/10 on the car with P7 225-50-15 in front and 285-55-15 on the backs.

Talk about maxing out the wheel width on a tire? Yikes.

I do like in particular that tire on the fronts because with removing the spring spacer that tire lowers the front of the car noticeably without the car looking slammed.

The nose is down there with the go carts, so I don't think it is unfair or derogatory to call it an Italian go cart at all?

It's about 41 inches to the roof with the spring spacers out of there.

I am going to change out the rear tires though to the MT LT 26 x 12R15 tires.

I think they are a better fit cosmetically to the rear and aren't as stressed out on the 10 inch rim as the P7 is.

I can't immagine that P7 on an 11" rim. Not arguing that the manufacturer isn't saying that it's ok or not.

I just know on the 10" rim vs. 285 relationship looks very precarious.


I also had bad experiences with BFG on maxing out the tire to the maximum recommended wheel width.

I had two tires split the treads and throw pieces of them off down to the belts on the carcass.

BFG refused to warranty them saying that it was a mis-application by me because it was not the RIM DESIGN WIDTH. Their chart clearly showed it was the maximum recommended width but they said that voided the warranty since it was more than the DESIGN width.



I can testify that maximing out the tire like that virtually eliminates any flex in the tire wall of the P7 which kind on makes me wonder why even bother with a radial back there at all. The fitment negates the value of the radial all together?

To me that is much more of what you would do on a race car rather than a street car, meaning there is NO play in the tire in the rear as a result...like a bias racing tire would be.


Voiding the warranty on a tire is a joke anyway. When it comes down to it you are buying a new tire because the warranty was based upon list price and a pro-rated number on it. No one pays list price on tires.
