215 or 255???

[GTR 94]

hi there i just have a question to ask. a friend of mine has a set of 17/45/215 dunlop semi slicks (not sure exactly what sort) but very square and look very much like track tyres. i am triing to decide whether to buy these and use just for track or buy a set of 17/45/255 street tyres and then i can use them on street and track. what would be best for track???

255 street tyre or 215 semi slick.

thanks heaps

im pretty sure a 215 slick would have a shit load more grip on the track than a 255 street tyre

depending on the wear of the semi slicks will make a difference as well and if it is old or not... theres no point in getting tyres that are just way too old i think cos they loose the grip and just wear away on track real fast... depends on the price as well though... dont be cheap on tyres cos thats the only contact you have with the ground....

215 semi will be better than a 255 street tyre but like totoro said wear and age are other factors.

Proper semi slicks are an amazing thing tho

But will they fit properly on the rims? 40mm (2 1/2 inches) of tread width is a fair bit of width.

40mm = 1.57inches

what width rims are you running?
