Hi, the 2 front tires on my GT could do with replacing soon, the back two still do have plenty of life yet (I really should have swapped the front with the back when I bought the car 6months ago!). But anyways, I'm not too sure what tyres to get next, there are 4 Dunlop sp sports on it now, in 225/45r17s. My one only complaint about the car is that the ride is alittle harsh, especially on any of the bumpy bad roads. Would anyone have any recommendations for a change in tyre size, or have any suggestions of tyres that they found were decent and good value? Would I get away with changing the size of the two front tyres now, and the rears later on? Cheapest I can find for the same tyres on it are from here Dunlop SP Sport 3000 A 225/45 R17 94 V XL, MFS Tyres » Oponeo.ie, my local tyre shop is looking €140 for each tyre (including fitting).
