Model s p85 (rwd 450hp, 600nm ,2.1 tonne)
A night and day difference to the stock 19"245/45 Goodyear rs-a2 all round .
Switched to a 20" ps4s staggered 275/35 . Which was the perfect balance between grip, asthetetics , pot hole protection and comfort compared to the 21"s .
Slightly less efficient and slightly more noise than stock ,which was to be expected with wider tires .
Rears wore faster , have another 1000mi probably , fronts 2-3k more but overall very happy with them .
