Thread: RR L322 Wheels on P38

Probably ride quality and that fact that anything over 18" on a P38a looks stupidly out of proportion as the car was designed in the 90's, anything over 18" looks bad on a D2 aswell, they weren't designed for them, so they look crap IMO, like when people put 18's on a HQ Holden, looks rubbish as they were designed for 14's.

Just my $0.02

It's all about 'period' modifications, once you start mixing styles the result is blurgh

Not to mention anything over 18 inch actually reduces the grip level on Tarmac on live axelled vehicles. Most people do not realise that you need a little bit of flex in the tyre wall to provide the optimum grip, too little and your tyres will skate in the wet. I'm personally not a fan of low profile tyres, as I recently found out from my cape trip that even the 18 inch rims cannot withstand a blow from a smallish rock or pothole.

Getting back on topic, if you keep your original 16" spare, make sure you also keep a set of wheel nuts and the original brace in the car otherwise you will not be able to fit it in case of a blow out.

That is a very good point

Its not the rim diameter with the axle type that reduces grip, it's the aspect/profile ratio of the tyre. I'm pretty sure Becca webster even beat the aussies offroad rock crawling using 20" wheels and live axles. The key number I think is either 50% or 45% in the profile for generating handling on the road - I think it was 50% but may stand corrected.

Wouldn't you want all 5 wheels alike? I read somewhere on here that if you have a mismatch, you could serioursly stuff the viscous coupling???

Ideally that's the best solution, but you can't always get a set of 5 newer ones as the fully sick bro's only buy 4 22's. It would/could also be difficulat taking the spacers off the spigots to change the spare, but yes if the rollidn diameter was out it would eventually stuff the VC.
