Alloys

[Deleted User 4371]

Hi all!

Quick question, as I'm getting myself all confused on some alloy wheels.

I am purchasing a second set of alloys (non-Jag ones) to put winter tyres on.

I have a MY24 P450 with 20" wheels.

All the sites I am looking at offer Alloys in widths of 7.5, 8.5 or 9.5 but I don't know how to find the widths of my current alloys.

I think I need two 8.5's for the front and two 9.5's for the rear but I was wondering if anyone here knew for sure?

Is it as simple as going out and measuring my current alloys?

Thanks

Scrap that...

Found a table that gives the information.. looks like I need bigger rims!

Have you tried these guys, looks like you just put in your details and choices appear in numbers. Would be worth giving them a call.

If I were looking to a set of dedicated winter wheels I’d look to smaller 19” tyre to get a higher side wall ratio.
Makes for better more compliant tyre, more pothole resistant and likely cheaper with greater range.
Just need to ensure your setup of brakes can accept the smaller rim.

Agree, best advice

Hi both, yeah thanks! I had thought about smaller rims and would prefer that however I'm not sure my rears could accommodate that, it's pretty cramped in the 20's as is.

I'll call the dealer and see if I can find out.

Half considering just leaving the rims I have and swapping out the rubber and storing the summers without rims.

@ MikeM thanks for the link will check them out!

I don’t think taking tyres on and off rims is a good idea for either the tyre or rim. Risk of damage to the rim from fitting, more balancing weights on and off and for the tyre, risk of tearing older rubber and setting up new stress and wear patterns in the tyre, unless for the latter you mark which wheel and location they are from.

Opinions are divided in regards to taking the tires off every season or owning two sets of wheels. The maker recommends rotating the tires every so often to allow for even wear, but our tires have different sizes front/rear and also are directional, so that means taking them off the rim anyway. I personally opted for spending more for a better quality rubbers (MPS4S) and keeping a single set of rims, plus my tire shop provides also garage for the spare ones for a modic fee. If it a specialized tire shop, than I´ll trust them not to "hurt" my rims in any way. This setup allows me to rotate every season. I have tried the other way with a different car before, eventually I had to take the tires off the rim anyway due to visible uneven wear, plus the saves I made by not having to go to a tire shop every 6 months did not offset the price of an extra set of alloys.
