Re: One for the tyre gurus

As I dont seem to be able to get any more that a 175 on a 5" rim and I have to keep my setup of 175 front and 195 back on my corelines ,what would be the best tyres to give me a bit more grip?

Out of intrest, what is the biggest size you can fit to starlines safely.I know Miss polkadot is running bigger rear tyers than standard

Hi,

195/45/15s will fit between 6.5J and 8J wheel widths

On 8J alloys I would suggest you are on the extreme, like with my alloys, this is really cool uber euro style but not to everyones taste i like

I think its also important tot point out that the speed rating of the tyre is also very important as usually the better the speed rating the better/strong the side wall profile/construction.

toyo r888's! they're a semi slick road legalo race tyre. The grip will be amazing- in the dry obviously!

Re: One for the tyre gurus

Carrying on with the can of worms. I did some further research
Online Tyre and alloy supplier - yes 195x45x15 will fit on a Rial Le Mans no problem one supplier said they were recomended by the manufacturer
Rial - the Manufacturer said widest section / profile 175x55x15 on a for2 or 185x55x15 on a Roadster. It is even in their fitment quide for 2007.
I know who I would beleive.
As the reason for all this was grip I am going to pursue the 195 route but I have started looking at fitting 5 stud adapters and 16" wheels. I have found two very nice wheels that will do the job at a reasonable price. just waiting to hear back on the offset of one of them.
Munk's suggestion of the toyo R888 whilst I am sure offering huge amounts of grip just seems a bit extreme to me, great in the dry on a race track but not up a muddy mountain road in wales in the rain. but then each to their own.
I will let you know what combo I go for

Re: One for the tyre gurus

Just make sure that you don't choose yokohammas in that case as they are notorious for being poo in the wet.

R888's give a suprising ammount of wet grip for a semi slick, but if you're doing mud, gravel & general muck i'd suggest toyo proxes or eagle f1's as a compromise.

PS i'd belive Rial over any online retailer, they know the tollerances of their wheels - specificaly when it concerns a particular car. Retialers are ****, even some of the smart retailers know very little on some subjects.

If all you are going for is grip and not looks, get some roadster lite steel wheels. Absolutly perfect offset is almost correct and will fit fairly wide tyres on the front. But, still expect some understeer as al the weight is in the rear of the car. If you want real front end grip put some ballast up front.

Re: One for the tyre gurus

In terms of tyres i was thinking of fitting Toyo T1-Rs. a lot cheaper than Goodyear F1s.

Re: One for the tyre gurus

I will be going for the Toyo T1-Rs (195/50/15's) on the rear but I don't know what to put on the front wheels. I have looked and there is only the Pirelli P9's, Bridgestone Potenza's or Yokohama AV's available on 175/55/15's. Are any of these tyres or any others going to be better than the standard Bridgestones's on the front?

Re: One for the tyre gurus

Whatever you do, make sure the overall rolling radius is about the same for the front and back. If one set of wheels rotate faster than the others the ESP will show an error and turn off.

Re: One for the tyre gurus

Does anyone know the percentage differance at which the esp starts having a fit. Rear wheels rotate faster than the front = wheelspin = esp cuts in. fronts rotate less than rears = lock up =ABS. I know it is a lot more complicated than that but fom an ABS point of view there has to be a definitive differential or even a speed at which it stops working over wise you would not be able to do full lock parking manouver. ESP would have to work in the samilar way
