Just had my rear wheels off and noticed that they have 'front' stamped on the inside. The front wheels also have this? Shouldn't the rears be stamped up 'rear'?

The size stamped on them is 8.5j x 18 H2.

Hi Kojak

I think it's got something to do with them being Tuscan fronts.

Regards
Simon

So are the fronts identical to the rears then? Rears and fronts are listed separately at TVR shop?

I was going to ask a similar question. Are the fronts and rears different sizes? I have 225's on the front of mine but they look very stretched to fit. I would assume this would affect any high speed cornering as the sidewall is already out of shape.

I have 255's on the rear and they seem to fit much better. I was wondering if there are narrower fronts to take the 225 tyres?

If that makes sense biggrin

Spiders were a Tuscan wheel that got retro-fitted to the Cerb and all Spiders therefore have Tuscan offsets (different front and rear) - when fitting to a Cerb it is often thought better to use fronts all round to keep the offset the same all round (as per standard Cerb). Some Cerbs do use a normal set of front and rear Spiders, but the rears then sit out further than the fronts and on some cars this has caused rubbing on the rear arches - no such concerns with fronts on all four.

Sounds just like mine, the front tyres look too small for the rims even though they are the recommended 225's, 255's on the rears look fine though.

That clears a few things up, cheers. Is it wise to put a wider tyre on the front to give the rim a bit more protection?

Indeed, spiders are a compromise on a Cerb, 8J front 9J rear suit the tyre sizes better.

225 is the prefered choice due I think to keeping the rolling radius the same, however as you both say it results in a stretched out sidewall as they are really too narrow for the 8.5" rim (all Spiders are this wide). You can go wider but (unless you go even lower profile than the 35) then you will start affecting the overall diameter and may cause more rubbing/turning problems etc (a Cerb with Spiders already has to have lock stops to prevent fouling the wishbones, which limits the turning circle).

Ultimately the Spiders are a bit of a botch to fit the Cerb, couple this with their propensity to buckle and the fact they are bastard heavy and you begin to question the logic of sticking with them. Go for a proper width rim with correct offset and you get a more natural setup and regain your steering lock to boot.

My car has front and rear 16" Spiders and even they rub the arches at the rear (mainly on the drivers side) but not to the point where it is a problem.

If (when ???) I change the rims I'll be going for ones with the front offset on all of them.

I had some 16" tuscan wheels on mine for a while (same offsets as the spiders) and had to trim back the inner wheelarch a little, this seemed to stop the rubbing, although different tyre types can change this......

I know, they look good, but they don't really work very well in practice. I'm thinking of going back to the 16" originals (saturns?) as I have a set that came with the car. The only issue there is finding tyres that fit. 18" tyres seem much a much more popular size than anything in 16"

Dont go for the 16" - Best wheel for the Cerbs are the original RL 17's

I've already got the 16's, they came with the car.

Think you can get Toyo Proxes T1-R's in the correct fittings for the 16's, should be less than £100 per corner as well - don't bother trying to find Bridgestones if that is what was on there, the later types were rubbish anyway seemingly.

Yeah, they're about the only ones I can find to fit. Nothing against proxes, got them on the wifes car, but it would be nice to have a choice smile

I had Goodyear Eagle F1s on my 16" wheels, they were very good. Others have had Falken 452s on 16" and spoken highly of them too. smile

225/45x16" front and 245/45x16" rear. Both the goodyears and the falkens (and also the bridgestones....) are 'Y' speed rated (300kmh+) the Toyo's are 'W' speed rated, so I never went for them in 16" sizes.

The S03 bidgestones are available in 16", but I found they tram lined like mad.

I only went for 17" rims and Goodyear GSD3s for changes sake, sometimes I wish I'd stuck with the original rims..... smile
