Hi all. It's time to look into winter tyres for my "new" Accord (still waiting to pick it up from dealer) - 7th Generation diesel tourer with 17" Pentas. I've got a set of 195/65 R15's Conti WinterContact which I used on my Touran (summer tyres are 205/55 R16) - so the same rolling diameter as the 225/45 R17 on the Penta's. I've been able to establish that the 2.0 petrol had 15" rims, but the diesel has bigger disks so I'm not sure if 15's will actually fit the diesel. Can anybody clarify? Otherwise its new 16" winter tyres (17" winter's are aorund £100 a corner) and a set of 16" rims (plus flogging exisiting winter's as a complete tyre/rim set). Also does anyone know about any limitations on fitting snow chains? One of the reasons I dropped to 15" rims for winter on the Touran (as well as cost) was the fact that chains won't clear the shocks with 205 section tyres. I guess it's in the manual - but I haven't got my car yet....... Cheers in advance for any help on these queries, Pete.
