What would be the recommended rear tyre size to match
Front 8.5j with 255/35/18
Rear 9.5j ????????

Thanks

You won't get much below a 35 profile, so nothing wider is going to match perfectly.

275/35/18 = +2.1%, which is just about acceptable (14mm bigger on diameter).
Thank you.. That was my guess as long I can find them In a decent brand I might try track semi slicks as the car is just a weekend toy now

Toyo should be able to supply an R888 in 275/35

I have Pirelli P Zero's and cannot be happier. I couldn't stretch to the prices that Michelin want for their tyres, but the wet grip the Pirellis have is insane and dry grip is progressive.

Thanks for the reply's, going to take the plunge very soon as slicks/rain is not good !!
If I was to go with NRF tyres what do people use as a get me home on roadside fix ?

Another question, Do the insurance company need to be contacted to say that I'm switching from RFT to NRFT, I'm with Admiral on a multi-car policy ?

Tyre weld and 12V plug in inflator for punctures and yes inform insurance company or even call them first to ensure there's no premium rise.

Have a look on eBay for Tyre Mobilty Kits. Any manufacturer (Kia, Ford, or whatever) will be fine.

Or just a big can (make sure it is the big one) of Holts Tyre Weld, or two.

Right, I've taken the plunge MPS4 NRFT fitted 👍🏼
Next question is what pressures do people run them at ?
I have gone up a size, Front - 225/40/18(88) & Rear - 255/35/18(94)

On a diseasil, I'd start with 35psi all round. Try that for a week, then fine tune to your liking.

Those front tyres really got a load index of 88 ?
Im not familiar with the PS4's but sounds a bit low for an XL tyre.

Your right, my fault the fronts should be 92 & not 88, rears are correct. Currently got 2.6 in front & 2.9 in rear but yet to drive anywhere until tomorrow.

Those pressures are rather high, especially the rears. unless u drive around with car fully loaded all the time.

I didn't spot that. Can you swap the fronts for 92 XL's?

If not, 35psi isn't going to cut it, probably too little pressure in a floppy tyre. :( Maybe start at 37 or 38 all round, and increase if you need to.

Is that 37-38psi on the fronts or all round ?
First drive today to work, much better ride on the bumpy roads but felt a bit understeary in the corners, might just be down to having softer wall tyres, or the fact that still got the sealant on the surface from manufacture, well see.
