Red face Tyre spec letters - confused!

I hit another effin’ pothole and now have a bulge in one of my tyres. They were all new in June last year and have only done 3,000 miles, so I’m wanting to fit the same type of tyre. The spec on the KwikFit invoice is 255/35R20 Pirelli P Zero 97Y XL JRS. Now, I get all the spec except ‘JRS’. I can find ‘MO’ and ‘AO’ but the only ‘JRS’ I can find isn’t ‘XL’.
So what’s the difference between the JRS, AO and MO suffixes, and would I notice any difference if I fitted an XL AO tyre?

AO is Audi Option, MO is Mercedes Option, JRS I believe is Jaguar option. They are basically different OE versions of the same tyre tweaked to suit the manufacturer's requirements for ride, noise, handling, etc. I would always be sure to run the same version on the same axle as they sometimes have slight variations in tread pattern, sidewall design etc.

Technically the correct tyre for your car would be the AO obviously, but I find the MO are just as good.

If the JRS isn't available in XL then I suspect its OE on something quite small (the coupe thing maybe), where as the AO and MO XL versions will be fitted to big heavy stuff.

I've always treated the manufacturer suffix as "optional", and have never had an issue with any of the tyres I've fitted to either the Audi or the Tesla, but that might just be me being a bit cavalier again, though I agree with MJ about matching on the same axle - XL is the main suffix I worry about, given the weight of the car.

It’s strange how much the price differs between the different suffix letters. And how much they’ve gone up in a year!

So why did they fit JLR tyres to my Audi, I wonder?

Probably what was either on the shelf, or cheapest. They probably don't know or care what those markings actually mean.

Just realised that the suffix on mine is JRS, not JLR, and that’s not on Sean’s list. Even more confused now

Sorry for the confusion Jim, but to make it better, here's another set of codes from another website that shows JRS! I even came across a site where they said that J inside a circle was also used for Jaguar. I would suspect that MJs response is the most accurate.
