Ultra High performance tires?
Hey Gents,
looking at a new set of shoes for the Jag. The size thats on there now is 255 45 18. I'm noticing that most ultra high performance/track tires only come in 255 35 18. What do you think about a shorter sidewall? Could I fit anything wider like 265's on there?
These ones are 255 40 18. liking the the Yokohama advan's

Do your tires rub at all?
I have 245/45/18 Contiental Contiextreme Contacts on my 2000 VDP and they rub just a little if I turn the wheel to the extreme left or right and run over a bump. It almost never happens though.

Make sure you get some good tires though. My car came with Pirelli P6 tires that were absolute CRAP. They had weak wet and dry traction at the limit.
It sounds like you are a performance driver? The prob with the Contientals is that the sidewalls are soft and can lead to rim damage on rough roads. Also, the tires are very quiet when they skid which can be a problem if you drive on a track and etc. They can give a false sense of having more traction than you really have. The Pirellis scream when they skid. Look for tires that scream when skidding if you are a track driver. I have a long wheel base XJ that is designed to understeer and plow in the corners. The sound of skidding to indicate understeer is pretty important when driving my car aggressively.
Its great to see that you are upgrading your car. Too few people upgrade their XJRs.
Has anyone been able to powerslide in a controlled manner in a XJ? I know that an open diff makes this pretty difficult. Its pretty hard to control my VDP in a powerslide. Its also close to impossible to get a VDP to even oversteer on a dry road without the throttle (actually I have never been able to do this at all).

Does this go as far as buying new tires every two years?....'cuz that's probably what you'll be looking at with ultra high performance summer tires.
You probably know that already but I had to throw it in :-)

Do you have a limited slip diff? The rear suspension on the XJ is primitive IMHO and gives too much wheel hop, well at least on my car. In comparison to the multilink rear suspension on the newer XJ, the X308 suspension does not keep the wheel perpendicular to the road as well when driving over bumps or through the corners. The rear doesn't slide at all on my car, but the throttle can break it loose pretty easily, and this is only a non s/c car.

In fact, even 255/40 is too wide for a 8 inch rim according to the vendor info shown at tirerack. 245/40 just squeaks in, and a 235 is a more reasonable fit for 8 inches. A 235/45 has almost the same revolutions per mile as a 255/40.

I run 255/35/19's being an XJR100 it has the Montreal wheels. The car loves good tyres.
I've used Michelin Pilot Sport 2's to good effect, excellent dry tire.
I'm now using Bridgestone Potenza RE50's, and these I find are even better in the dry.
(I don't use the car in rain)
I'd recommend these.
Whatever, they'll have to be Y96 rated, extra load. Because of the size and speed of your car, use nothing less. Period.
