Finally changing my Pirelli P600’s from 08, I know long over due, any suggestions on a 235/60/15 that won’t break the bank? Thanks

 

I just Googled "235/60x15 tires" and there are a number of choices out there for about $100-$200 each. BF Goodrich, Hankook, and some Brand-X choices.

None of them are high speed rated tires, which might not be a concern for you. They're rather conventional tires dressed-up to look like a high performance tire. That doesn't mean they're bad tires and if you're a gentle driver most any of them would be OK, I reckon.

Others will chime in with specific experiences, I'm sure

to add all those mentioned tires are fine up to any posted hwy speeds you will encounter unless you are on the autobaun or tracking your xjs but then you would have specific tires for track. for 99% of xjs owners they are fine.

 

I decided to go with the Hankook tires through Amazon at $453 delivered I thought that was a pretty good deal.

 

what model?

 

I went with the Hankook 98T KINERGY ST.

 

As an FYI for this side of the pond:
In the UK and the EU it is illegal to fit tyres (tires) that are not rated for the top speed of the car.

 

interesting, here in the states that’s not a requirement.

 

I'm going to go out on a limb here: Speed Rating is useful, and if you go below the recommended speed rating, that's on you. But Load Rating... now that's where you want to be paying some attention!

 

1653lbs on the Pirelli
1700lbs on the Hankook

 

Vredestein has some of the best tires Ive seen on Jag lately. I have 16” wheels so options are a little better

 

Actually, it is illegal for a "business" to put on lower rated tires, but a lot of people don't follow the law here.
If a customer insists on it, we make a note of the speed and load rating on the repair order, and we make them sign a waiver acknowledging it.
It's a shame that the US and European tire makers discontinue them and force people to go to Chinese/Korean and/or lower speed/load rated tires just to keep the car on the road. Goodyear, Michelin, Pirelli and a bunch of others are big offenders.

 

The majority of these old Jags are driven like there's a bowl of goldfish on the seat. Speed ratings are not a big factor for most people.

Which is the reason for lumpy tickover in most cases! The problem over here is that speed limits are so low and so heavily enforced it is more and more difficult to give my car decent excerise!

 

Lucky you.
235/60/15 seem not to be available in the UK. One well respected classic tyre specialist recommends Pirelli 205/70/15 as a replacement for the XJS but they are £323 each. Would be interesting to hear if anyone has tried this size.

There is the option of swapping to 16 inch rims as recommended on another thread on here. There is a lot of tyre choice (225/55/16) and at a much lower price. Unfortunately that means buying a set of second-hand 16 inch Jaguar rims and (of course!) these are way more expensive than 15 inch rims.

Let us know how you get on with the tyres.

I think this was the original XJS size, my 15 inch starfish, when I had them on the car, used this size. I swapped to 16 inch because they were either NLA or, as you indicate, idiotically expensive. FWIW, the ride on the XJS is unbeatable on this tyre size, IMO. High speed stability is noticeably better on the 16 inch tyres and rims (although not at all bad on the 15s) but the ride is, while pefectly fine, not quite up to the magic carpet ride the original tyres give.

 

Brilliant comment, Doug, I shall (try to) remember it!

 

How would 16 inch Tyres affect what you see on your Speedo?

Could you for instance be doing 35 Mph on 16 inch Tyres when your Speedo seems to indicate you're only doing 30 Mph?

Pretty much Zero Tolerance in the UK

 

Yes. But if you run lower profile 16s you can get pretty close to original diameter.

OB,

As a comparison between 235/60 tyres on a 15" rim, and 225/55 tyres on a 16" rim:

The 16" option will have a fractionally lower circumference. My rough calculations indicate that the 16" circumference would be 94.397% of the 15" circumference.

So, (again roughly!) the 16" option will mean that you are travelling slower than the speedo indicates.

At indicated 30mph, you're doing 28.32mph
At indicated 40mph, you're doing 37.76mph
At indicated 50mph, you're doing 47.20mph

So, you should be safer from getting caught speeding, if you just go by the speedo figure!
