18" Tyres on a 147 - Speed Ratings?
Sorry, another question after a couple of days ago.
When my car was being taken in for the ABS/VDC failure to the checked, they reccomended me to buy some new tyres as they were 'getting there'. I'm thinking about replacing the 225/35/18s on my 147 with some 225/40/18s, but the weighting I believe on these new tyres is 88W (and ZR rated) - but Alfa recommend 91W ratings.
Anyone got any idea if these will be alright? Surely if they are ZR rated, it wouldn't make any difference.
