'Scuse the dumbarse question but I need to know what FACTORY FIT wheels were optional for the 4.2 Cerb (1998)
Reason - I have 225/45/ZR16 front and 245/45/ZR16 rears
BUT
I'm not happy with backend traction under heavy acceleration, even in a straight line. I really want a set of black SP12 spider 18" rims with 245/35/ZR18 front and 265/35/ZR18 or 275/35/ZR18's on the rear.
Now I can get said tyres - Michelin for FREE as long as they are an OEM size for the vehicle in question, if not it's going to cost a fortune in rubber on top of the cost of the rims.
Cheers

Be carefull when you get your wheels, it is not just the size and width that you need to watch out for. The cerb should be delivered with 4 front wheels, this may sound daft but when I got mine it had 3 front wheels and one rear wheel. There is a different stand-off on the rear wheels and on the cerb it causes the tyre to rub the inside of the wheel arch.
I thought I must have had a soft damper or something as every time I went hard round a left turn I could hear the rubbing. When advised that there was nothing wrong with the suspension and after closer inpection we noticed that one rear wheel stood out more than the the other by about half an inch. The rim and width were of course the same on both sides however the wheel thickness in the centre (stand-off) were not. Spiders apparently come in front and rear types. The Tuscans i think have rear wheels on the rear (oddly enough) but the cerbs have fronts. It must just be because we are used to things being less than straight forward!!

I wouldn't expect a wrong offset in a set of SP wheels, since they're car specific.
Correct. Another point of note about V8Cerbera's original post is that 245s won't fit the front. They certainly won't fit in the arch on spiders without surgery and although they *may* fit on the SP12 rim, it's unnecessary. Another point about a 245/35 is that, apart from its width, the rolling radius is bigger than a 225/35. When the 225 is sitting correctly on an 8J rim instead of pulled across the 8.5J spider, it works properly ergo the desire for improved handling/grip is satisfied by using a 225 properly, not by adding a 245.
Only TVR would use the same size rim (8.5J) front and back and attempt to set the handling balance on tyre width alone.
A Cerbera running 225/35 front and 265/35 rear on wheels of the correct offset for the chassis geometry has a really muscular stance - it looks right. Handles properly too - that's why I fitted them to my Cerberas.V8Cerbera said:
So you're suggesting 225/35/ZR18 fronts and 265/35/ZR18's rear? Did ANY cerb roll out of the factory with these on as standard? I need to know or I won't be getting free tyres.
Yes, I'm suggesting 225 & 265, recommending even. The 265 rear is a useful upgrade IMO - not essential though!
No, they don't come as standard. 225 & 255 did - which is nearly as good, especially if the tyres are free!
Get a set of 225 + 255 for free. They'll be fine on the car. OR Get a set of 225 + 255 for free ...then sell on the 255s and put the proceeds towards a pair of 265s?

Sounds like spiders fitted after original wheels.
When i bought the car at 2 years old i was advised that these were the originals as the dealer had to put new tyres on all round. I suppose that it is possible that the dealer had to change one because they did refurbish two others. My point was just to be careful because there is a difference. sorry, forgot to mention mine is a 2003 with 255/35zr18 R and 225/35zr18 F

Lol. There is no way I'd sell a set of 255 Michelins and put lower grade 265's on. I'm well aware of tyre grip levels and IMO, people scrimping on their tyres is a major cause of accidents, especially in the wet

Who said anything about scrimping? I assumed you'd flog the 255s and top up the difference to get the same in 265s?
Which MIchelins are you planning on getting?
