What a superb site many thanks. I spent about an hour in between it and eBay, getting an idea on prices with different profiles etc.
For example a set of 4 x 225/55/15 costs Ã‚Â£225 delivered (Sunew), I've had them on the backs with over 30,000 miles and still VERY Legal. I got 24,000 out of the fronts, so although they're cheap, they work for me.
Go up to 255/55/17 and the price increases for 4 to Ã‚Â£332.
I expect though that my mpg would decrease as the 'footprint' of the tyre enlarges creating more friction. Alternatively though, the enhanced road holding would be excellent I imagine?
Then we get into the insurance malarkey of them not being standard - blah, blah, that'll be another 80 quid on your premium thank you.
Interestingly, and not in the least connected I had a cig lighter phone charger delivered today. Upon opening it, the first thing the instructions advise is 'DO NOT EAT THIS PRODUCT'. I told my mate who's coming to stay next weekend that we'll have a few pints, and then come back here for a nosh, as I've got a couple of phone chargers and a box of DVD's in the fridge!
I blame it all on the Belgians!
