Tyre speed rating on Grande Sport 130

Hi,

Ive got the Grande Sport 130bhp and was just checking the tyres.

At the front I have 205/45 R17 88 W
At the back I have 205/45 R17 88 V

Couple of questions! Do I need to stick with V rated at the rear, comparing the prices of W and V and its quite considerable.

I seem to have a slow leak on one of the rear tyres, have to keep pumping it up every couple of weeks - loses upto 10 bar. Do places like kwik fit/national do slow puncture repairs? Ive checked and cant see any nails or anything similar.

Thanks in advance

Hi Mick,

Certainly wont be going that fast! Im guessing it wouldnt cause if I changed both the back tyres to W's then? (About £100 cheaper per tyre then V's!)

£100 each cheaper? Lol! Your looking in the wrong places methinks! Just looked on bkackcircles, Uniroyal Rainsport 88v is £104 each, 88w is £111? So where's the huge price difference? The w rated is dearer....

From looking on blackcircles Toyo t1r in 205-45-17 88w seems best value at &84 each delivered

i would have thought the higher speed rating tyres would cost more than lower speed rated tyres .

Re: Tyre speed rating on Grande Sport 130

If you change tyre rating from that of the manufacturer fitted equipment you should notify your insurer, technically a modification, you remember how arsey they got about Winter tyres...

What brand/model are you running on?
What tyres are given in your OH? (Donít think my edition shows Sporting)
Are you obliged to run on UHP tyres with a GP Sporting 130HP?

Losing 10 bar? Wow, I only put just over 2 in mine :-) slow puncture may be cured with a can of tyre sealant. As for speed rating technicaly you should stick with the original, same goes for load rating too but no one ever checks these details.
