Stretched tires legal & safe?

What are stretched tires and are they safe? A question we get asked over and over again but there are 2 schools of thought on this subject and we aim to cover the pros and cons in as open and unbiased way as we can.

This is a tyre which has been fitted to a much wider rim than it was originally intended or designed to fit. Stretches vary from an inch to around 3 inches. It has gained a lot of popularity in VW circles and the look is really starting to take off.

Low ratio sport gearbox setup and selection.

Gearbox – Lower ratios give better acceleration times and lower fuel economy. Six or seven speed boxes are better matched to modern engines.

Most street applications are closer 1st and 2nd gear ratios for that off the line 0-60 boost or for the fast exec a lower 2nd and 3rd ratio give improved overtaking flexibility and 30 – 70 mph acceleration with a high 4th and 5th gear to give motorway fuel economy.

How to lower the engines compression ratio

Reducing the compression ratio is required if you want to run a high boost supercharged engine. High compression NASP engines are quite efficient but when adding forced induction you want to lower the compression ratio.

The compression ratio has a dramatic effect on an engines performance and the problem of knock, (where the air fuel mix prematurely ignites) is controlled to a large degree by the compression ratio.

Stage 1, 2 & 3 tuning mods explained

We hate to shatter the illusion but they are fairly meaningless terms if applied to power gains and cannot reliably be used to explain how much power a modification adds. There is no consistant difference in part makers between their classifications of stage 1 stage 2 and stage 3 mods.

Some tuning companies will just box their parts in packs labelled stage 1,2 and 3 and maybe even 4 or 5. Such labeling is as helpful as a product number and should not be taken as any sort of guarantee of the power gains or suitability for your car.
