I've been sorting out my garage and am makng some time to osrt my vehicles out. 
I need tyres on a couple of things and have spares, but not the exact fitting.

eg. I need 2 tyres on my Golf VE and they are 195/65/15.
I have 2 spares laying around which are 205/60/15.
If I pair them up on front or back, will they be OK?

They're pretty close overall rolling radius so it should be fine imo.

205 X 0.6 = 123mm sidewall
195 X 0.65 = 126.75mm sidewall

You'd be adding 3.75mm to the rolling radius so your speedo might be a tiny bit out, but it's not huge.

You will eventually end up upsetting the ABS, I'd have thought.  By law the same profile must be on the same axle.

Best way to lose weight is not drinking mayonnaise/cheese/beer everyday.
