[QUOTE="Alex VW Heritage, post: 413687, member: 19109"] Larger tyres is a greater rolling radius and taller gears has the same effect. This will mean for the same RPM you travel at a higher speed. This in turn means you will run cooler, so higher the rear tyre profile and gear ratio the lower rpm needed to run @ 70mph so lower rpm is therefore cooler. 50mph wil probably mean you run too cool, as you will loose fan speed, ideal is 3400rpm to create a good cooling effect. Its is a complicated subject but one i love to chat about, feel free to email alex@vwheritage if I can offer any further advice. Cheers Alex [/QUOTE]
