Hi guys, I wasnt 100% sure what the 91, 94, 98 etc numbers referred to on a tyre sidewall so a quick google search taught me it was the load rating of the tyre ie how much load it can safely take.

So two questions I still have, unanswered...

1, I presume 'load' simply refers to how much weight you are carrying in the vehicle, over that axel?

2, does that then mean the higher rated tyres have a stiffer sidewall ie a 98 would be stiffer than a 94 to take the additional load or is it not as clear cut as that?

Thanks in advance.

1. Its also the weight of the car, not just what your carrying.

2. The speed rating will also have a slight difference on the sidewall strength, but yes to an extent a higher load rating will have slightly stiffer sidewalls when compared to the same manufacturer. A 98 rated tyre by Michelin will have softer sides than a Bridgestone, the Michelin will provide less noise and more of a comfort ride, the Bridge will provde more more feel and will be more planted in the twisty bit's.
