Jedino ispravno rešenje je imati sve 4 nove gume, i to isti model (poželjno minimum srednje klase).
Bez uvrede, ali bolje obriši ovo, jer temu čitaju i početnici, nećemo se zezati sa takvim stvarima.
Niko ovde nije napisao da napred treba ostaviti skroz potrošene gume, nego da nove (ili manje potrošene) treba montirati pozadi.

You are recommended to fit the new tires (or the least worn) on the rear axle of your vehicle, whether it is a front or rear, 2 or 4 wheel drive.
This ensures better control and handling in situations of emergency braking or on tight bends, particularly on wet surfaces. The loss of rear wheel grip is not easy to be controlled by the driver. On a bend, this means that the car oversteers and the rear of the vehicle starts to skid. Drivers are tempted to brake and turn the wheel too hard... and they end up going into a spin! Only an experienced driver would have the reflex to do the opposite, namely countersteer and accelerate.
Loss of front wheel grip (understeering) is easier to correct with the steering wheel, whilst taking your foot off the accelerator. Fitting the best tires at the rear, the driver enjoys a substantial gain in safety

Tires provide the most traction in hazardous road conditions (wet, slushy, snowy) when they are new, and have full tread depth. By placing the newer, better tires on the rear of the car, we're maximizing the control and traction available at the rear wheels and keeping the rear of the car as stable and planted as possible.
For most typical, everyday drivers, a loss of control at the rear axle isn't something that’s easily managed. A loss of traction at the rear of the vehicle often results in a spin, and/or an unwelcome off-road adventure – while if the front tires “wash out” due to a temporary loss of traction, driver intervention isn't generally as urgent, or quite as difficult.
