I've seen some new wheels being sold locally off a 23 plate sport

5126 wheels fitted with 275/50/21 tyres
The tyres on my 2006 supercharged l322 are 255/50/20 , I've rolled them up against the car and they're a lot taller

Do they fit as they look like the fill the whole arch and then some

Click image to enlarge

They look more than an inch bigger

They are 31.8" your standard ones are 30" I had 32's on Fatty offroader and had to do some trimming and modification to the petrol filler pipe...

At an indicated 66mph you will be doing 70mph....

Can be done but not recommended Pete
I now have permission from the boss to use Y.O.L.O. Enjoy life

I’ve previously run 275/55/r20 on the L322 … which is the same height and width as what you have. It’s basically right at the limit of what the L322 will take as stock.

From memory … the rear wheel arch on the inside there is a bulge for the fuel filler pipe. You need to either heat that up with a heat gun to soften it and reshape it out of the way. I think it’s also possible to use a screw to pull it inwards as well. ( cant remember what it screwed into though )

On the front struts there is a cone shaped bit of plastic moulding on the underside of the air spring that points downwards at the tyre. I had to snip these short to fit the tyres in. The cones aren’t structural, I think they were just locator lugs.

The newer sport rims might sit out slightly wider than the stock ones (lower offset). The benefit being that this gives more clearance between the tyre and strut. The disadvantage is that pushes the edge of the tyre closer to the front of the wheel well on turning … it possibly it may rub slightly.

In terms of driving … expect it to dull the acceleration / handling. Expect the possibility of slight rubbing.

Lastly consider the spare. I’m currently running 1 size up from stock, but I only have 4 wheels / tyres in that size … If I needed to use the stock size spare, it’d potentially cause issues longer term ( but would work enough to get you to a safe place )

Edit - found an old picture:

Having had a think about it , it's more trouble than it's worth

I've got some L405 wheels which I think I'll stick to

Thanks for the replies
