Hello,
The Pirellis on the car currently are 255/40R18 and pure and utterly rubbish. They have developed a series of uniformity harmonics decent of a punk band concert. I have had good luck with PS2s in the past on my NSX and was wondering if anyone was running PS2s one their Jaag.
Thank you in advance for any insights.
Alex

 

Well, on my XJR, i'm running the Michelin PS2's, 255/40 though, myself and love them plenty. Though of going wider but I don't believe the stock rims would fit them from the research I had done.
Greta tires and great grip and a bit quieter than the pirellis i had when I got the car!

 

I looked closely today and front tires are shot... I found a good deal on a set of Michelin Energy 3 in 245/45R18. A wee bit smaller and shorter than stock.

I have found contradictory info on the rim width on a 98 XJR... 8" or 9" ?

 

98 Xjr would be 18x8'' on all four corners, only XJR R1's and 100's have different size rims. I think all 98's XJR's came with Penta 5 spoke wheels. 275's would be way to big, 245's work fine.
