A fellow enthusiast who shall remain nameless has offered to sell me a pair of 16" original griff 500 wheels.

I was considering putting them on the front of mine, thus replacing the original 15" ones.

What size tyre & type would you recommend me putting on as the originals on the 15" are 205/55/15.

If I was to go up a width ie 215, would it make the steering much heavier?

Any thoughts / recommendations or things I may have overlooked???

ps I have currently 225 SO3's on the back end of mine. With this in mind should I stick with the Bridgestones or are Toyo's just as good??

Why not swap the fronts and rears around and see how it feels? Wouldn't do it permannetly but would give you some idea.

For a permanent thing you need to go to a lower profile to compensate for the 16 inch wheel. This will make things harsher. Tyre diams and sizes are in the bible, on my website (tyre faq) and you can download the excel spread sheet to play what if games.

I would go with exactly the same size tyres you're using on the back - that seems just about the optimum width for those rims.

I suppose they'll fit OK when in the garage - but I'd imagine later you'll get to a corner or a bump & find they're too large

Clearly you do need to check for clearance through the full range of steering and suspension travel.

Wouldn't 225wide tyres on a non pas griff be too heavy to turn at low speeds

Good suggestion steve I will try swapping them around but am a bit stuck for time & am away this weekend & need to make a decision on whether to buy them or not pretty sharpish.

I thought the last 100 griff 500's had 16" wheels all around? Does anyone know what size tyres these had on the front. These would have being power assisted though!

EDT - I would be reluctant to put 16" wheels on the front if I thought the handling & ride would suffer? Surely not if on the last 100?

I put 16 inch all round on my Chimaera and it tranformed the handling, it is brilliant. Also the look was greatly improved, no more dodgy 'hot rod' look

the rears have a different offset, 35 to 25.

i don't think they'll fit as they are. i beleive they'll foul the battery box or inner wing.

i've got some for my front and from asking various learned people, i need 10mm spacers on the front.

griff 500 currently 225 (15) / 245 (16)

will be 225 (16) / 245 (16)

i reckon a 1-2lb pressure drop should maintain footprint.

That's what I'm running on the V8S and I don't have any problem with it. Doesn't mean everybody would get on with it, but personally I think it's fine.

I run 17” wheels on the front of my non-PAS Griff 500 with 215 width tyres and (much to Steve’s chagrin) I can assure you it does not detrimentally effect the handling, in fact since having the geometry re-set and wheels well balanced at Racing Green the steering and handling feels the best it ever has. As has been said the rear rims have 35mm offset so you will need a large spacer to be able use these on the front. Remember the centre bore of the rim must engage with the raised flange in the centre of the hub, and a normal 10mm spacer will not allow you to achieve this – the studs hold the wheel on – the centre bore seats the wheel centrally on the hub and takes the weight , there are specialist spacers available which presumably have different diameter centre flanges and lips etc. to achieve this but I don’t know anything about these having not used them. I guess if you decide to go for it you will need something like a 215 40x16 but I do not know if this is available from Bridgestone. (and their web site seems crap) Cheers Rich…

Rich,
Im using aftermarket rims on the front with a 35mm offset(I won't bore you lot with pics again) and don't need a spacer. Is the recommendation for a spacer one of geometry & handling or clearance? If clearance I have no problems with the offset and presume TVR did not fit spacers to the last 100 Griffs using 16" fronts with a 37.5mm offset but don't know for sure.
If any lucky owners of one of the last 100 would care to check, this could clear up a lot of grey areas on this thread.

Oh I dunno! Maybe it's 'cos I have 17" rims not 16"? Maybe it's 'cos mine are 8" wide rims at the front and the rear 16" ers' on a Griff are only 7.5". Perhaps its the extra half inch that makes all the difference? But then who knows, and remember this is TVR we are talking about, I found my wheels rubbed on one side only. Anyway I am always told that an extra half inch makes no difference er err missus . Rich...
