Looking for a bit of a steer from folk who have recently bought tyres for their 360.

Based on feedback on FerrariChat I had wanted to get a set of Pilot 4s. These would be for the standard starfish wheel.

The sizes being used on FerrariChat are 285/35/18 zr XL and 225/40/18 zr xl. Although not the exact oem size these maintain the correct ratio to front and rear so as not to trigger any abs/acr issues.

However the 285/35 is not available in the uk, but is in the US. Additionally speaking to a tyre specialist these are the wrong load rating for the car and would invalidate the insurance if it came to an incident.

Apparently I should be staying with the manufacturer specified tyres.

What are my best options now, with more modern tyres? And does using a tyre outside of the original manufacturer specified tyres constitute a modification?

Yeah, of course they would......... I had PS4s on my car, when the only manufacturer approved tyres were P-Zero - the insurance company couldn't have cared less. It was never questioned or mentioned.

For what it's worth - much as I generally hate them - I did find that Pirelli worked OK on my 360. They did seem to suit the car.

What I found odd (at least on the 430) was different tyre pressures for different makes of tyre.

I still have the Pirrelli's on mine and I never felt an issue with them, but then I am crap driver.

The sizes you list don't seem consistent with other websites e.g. https://www.wheel-size.com/size/ferrari/360-modena...

The PS4s fronts are available in the UK, the rears (non runflat) can be hard to get. In my experience PS4s are far far better than Pirellis. Isn't Y speed rating equivalent to 186 mph - which I doubt you will be exceeding, even if other websites say 360s are rating Z.

Anyway, it looks like PS5s are now available for 360s in the UK?

That’s right. These aren’t the standard sizes, but what will fit the wheels and maintain the front to back ratios.

Hi, did anyone fit PS5’s on a 360 in the end?

The P Zero’s just do not work on the track and I really like the PS4/5’s on my other cars.

Thanks
Spencer
