Hello all,
I am in the process of upgrading the tires on my 2WD 1989 Westy
to 215/75R15 size (diameter 27.8").  My current spare is 185R14 (diameter
25.7").  I am wondering if using this spare for a short drive in case I
were to get a flat would potentially cause engine or drivetrain damage of
any sort due to the difference in tire diameters?
Thank you.
