I am about to buy a new set of tyres for my Ford Focus Zetec-S MK2 facelift. At the moment I have two different pairs of tyres (205/50/17) with 93XL load. The confusion comes from blackcircles.com, which determines the standard size and load for my focus as 205/50/17 W 89.
The problem is that I cannot find a desired tyres with W 89 index, while there are plenty of XL tyres of 205/50/17 size.
What would you do if you were me? Would you buy W 89 index tyres only or it is perfectly ok to go for 93XL tyre? Are there any implications on insurance, car performance, etc.?
