Ne sporim tvoje ogromno znanje, iskustvo i želju da nekome pomogneš dobronamjernim savjetom, ali ipak ne možeš znati baš sve. Taj savjet da je gume opasno rotirati mi je prilično neutemeljen. Ali, dobro. Svatko neka radi kako misli da je najbolje. 
Samo bih se želio nadovezati s idejom gdje Michelin, pored rotacije guma, savjetuje sasvim novi model rotacije.
Logično je da se od četiri gume najviše potroše one na pogonskim, u većini slučajeva su to prednji kotači. Ako se gume redovito ne rotiraju, u jednom trenu će prednje postati neupotrebljive, dok će stražnje biti relativno upotrebljive. S obzirom da se većina zbog racionalnosti i uštede odlučuje na kupnju samo dvije nove, Michelin savjetuje (pazi sad!) da se nove gume stave na stražnje kotače, a stare na prednje kotače. Dakle ne obratno kako je u narodu uvriježeno.

Why mount new or less worn tyres at the rear?
Whether you have front or rear wheel drive, we recommend that you use newer tyres for the rear set, for extra safety in unforeseen or difficult situations (emergency braking, tight bends etc) particularly on wet surfaces
Numerous tests have shown that it is easier to control the front wheels than those at the rear.
Front tyres generally wear quicker than those fitted at the rear, particularly on front wheel drive cars, which are currently in the majority.
New tyres fitted in front :
The performance of the car will change, because the front/rear balance will be reversed. The driver, used to a car with less grip at the front, will therefore be taken unawares.
On a slippery road, the rear of the vehicle will lose traction before the front.
The driver will not be able to control the rear and will be tempted to accelerate further, which will amplify the spin effect. Only an experienced driver will be able to recover from this dangerous situation...
New tyres fitted at the back :
The handling of the vehicle will be similar to that known by the driver before the tyre change, because the traction balance will be the same.
Rear traction will be better and the driver will be able to control and steer his vehicle easily by decelerating and turning the steering wheel in the direction of the bend.
This is why Michelin advises you to reduce risks by fitting new or less worn tyres at the rear for :
- a better grip on bends.
- extra safety.
