Tyres: Different Size Spare

[Mat]

Following from an earlier thread, i had a look at my spare.

 

Spare tyre: 195/65R15

Wheels: 205/55R16

 

So, my wheels are 16 inch diameter, but my spare is 15 inches. Does this not mean that if i get a puncture and swap that tyre for my spare, that the opposite wheel will not touch the floor?

No mate, Tyre sizes mean the rolling radius is pretty much identical. Lower profile on the 16 than on the 15 thus much higher sidewall you can get 19's on there with only a marginal different in rolling radius but it would not be a comfortable ride.

Thats ok then - cheers

the suspention should compensate and balance things out. If you do get a puncture get it fixed as soon as possible...pretty simple stuff
