How do I know what load tyre to go for?

91 or 94? Does the load have a bearing on wear rate?

Car is a 2007 Civic diesel.

All help much appreciated 😀

It's just a speed rating

The load rating is how much weight the tyre is rated to support. The speed rating is the letter after the load rating. Michelin website reckons 91. Shouldn't think it has any bearing on wear rate.

Load and speed ratings should be as per the original fitting to avoid problems with insurance payouts.

Load rating should be per the original fitting. Any speed rating is legal, as long as you do not exceed the rating. I would still check with your insurer.

For a normal car (eg civic) 91 is probably loads. Check your owners manual. I'd bet £1 you are fine with 91.

It really only comes into play for heavy cars (eg 4x4s, bentlys) and most importantly - LCVs.

It has nothing to do with wear or life.

The full spec should also be in your owners manual. Beat me to it ^^^ 🙂

No it's not. Be careful of giving advice on subjects that involve safety of others when you don't know the answer for sure.

Speed ratings are the max speed rating for the tyre and should be higher than the vehicle max speed.
Load ratings are the load the tyre is rated to within its specification (i.e. max load at max speed). Higher load tyres tend to have stiffer sidewalls, more responsive turning but also slightly faster break-away at the limits, but most importantly on scottish roads they're a bit more pothole resistant due to the stiffer sidewalls.

None of it changes wear ratings necessarily.

You need to ensure you're not changing your load rating to one lower than specified by the manufacturer, higher is fine.

I did wonder if load rating affected the sidewall thickness and hence the ride. But not for very long 🙂

Deffo a load rating.

94 can take more than 91?

Wonder how much the difference in kg per tyre.

55kg between 91 and 94, 94 being 670kg.

Yes. Google is your friend. Each tyre takes X kg at max speed kind of thing. The higher the number the bigger the tested load.

#Edit - beaten to it.

I did Google!

Hence the edit lol

I should have said I'm off to find out. Glad I'm using the right tyre load.
