Hi guys,
The short version is, how much leeway do I have when mixing tyre sizes on a Classic? (and don't say none, or the thing would surely crap out any time you run on a spare that has a few mm more tread...) :twisted:
The long version is, I'm currently running on 205/80R16 (of different brands, and different ages, and therefore different rolling diameters anyway). I'm looking to buy 4 new tyres (2 this month, 2 next month) and use the current tyres as trailers and spares.
A 235/70R16 would give me a rolling diameter of 734mm, ie about the same as the current tyres, and is probably the safest option. I wouldn't mind gaining a bit of height though. Trouble is that I'm not going to buy new tyres for spares, so my spares will need to mix safely with the new ones.
Anyone care to put some kind of a figure on what would be an acceptable variance?
(FWIW they're the stock 3-spoke alloys, and I'm looking at Goodyear Silent Armors).
