Silverstone Sport R88 Tyres 8 are being used this year in the MR2 racing series. Some of the heavier MK2s have found the wear rate quite challenging, but the lighter MK1s are wearing well. We've raced in the dry at Mallory (excellent grip, tend to throw lumps off when hot!) and at Brands Hatch in the wet (very very surprised at how grippy and progressive they were in damp and greasy conditions, have not yet experienced large amounts of standing water). All in all have found it to be a good tyre.
