I'm currently running a set of 255/85/16 BFG mud's on mach 5 wheels, couple of them have suffered sidewall damage from offroading, one of them is still tubeless and beginning to leak. Obviously if i whack a tube in there this will fix the problem, but it got me thinking - should I really look at replacing the whole tyre bearing in mind I occasionally have to travel long distance at motorway speeds, putting a lot of stress on the tyre. Would like to keep using the tyre if I can as theres loads of tread on it. What's the best thing to do??
