new tyres pulling

As the title says I just had new tyres fitted admittedly they are special tracks 265/75/16s before I had them fitted braking was fine but now when I brake with them on my truck pulls quite harshly to the right under braking. I rebuilt the swivels a few weeks back minus wheel bearing but surely its not bearing as it done first time I used the brakes leaving the garage. Any help would be good. Thanks

i'd take the wheels off and check the calipers for sticky pistons and general brake checkup

the new tyres might just show the problem more.

Swap the wheels side to side, not unknow for a tyre to be faulty.

Il check the calipers as thats my first suspicion. When I first had the truck the same caliper wouldnt release and changed the caliper it was just strange that it started to pull like that so sudden.

could be as simple as uneven tyre pressures.

had a similar problem with mine , would like to say I found the problem but to be honest never got around to it before drowning it in water and not tested new engine yet ,

mine was uneven braking randomly on both sides , one time right , then right then suddenly left !

mine had all brand new discs,callipers and braided brake pipes just fitted if that helps

My 90 had uneven braking when I put new tyres on it - however, I found the problem not to be that of the tyres and that brake pads on the front passenger side were very worn and uneven and the disc was grooved. Bought new pads and discs and all seems to be ok.
