18" tyres sorted 245/40 R18's Thanx Guys

[M 80NGO]

Finally got my tyres sorted today and hey presto the speedo is 3mph out compared to satnav i've gotta say a huge thankyou to all you guys that gave input to my origional post and to Brett at Guyhirn Partworn Tyres he took my 5 month old 225/40 18 Runways and replaced them with pirelli PZero 245/40 18's with 6 / 7mm of tread on them and all it cost me was £80 compared to a full new set quoted from ATS at £450, on the way home i had satnav fired up and she's 3 mph out ie when the speedo reads 70 satnav says 67 so i'm well chuffed, the ride is also quieter and smoother than before, Brett took the time to show me all the tyres that had been recomended by fellow Bongoliers we stood them all side by side and discussed the pro's and cons, Yes 225 / 45s would have made the speedo even nearer but i'm lovin the phat wide stance of the 245,s
