4.3 Precat Tyre sizes

[leerdam23]

Hi all..


Need to pick your communal brains re Tyre sizes. What is recomended for a 4.3 precat on Ozz rims.

[davep]

Some info I have on Griff pre-cat/500 tyre sizes for 15x7 and 16x7.5 wheels:

- 1991: 215/50 ZR 15 (F), 225/50 ZR 16 (R)
- 1993: 205/55 ZR 15 (F), 235/50 ZR 16 (R)
- 1997: 205/55 ZR 15 (F) non-pas or 225/50 ZR 15 (F) pas, 245/45 ZR 16 (R)

I currently have 225/50 ZR 15 and 245/45 ZR 16 on my pre-cat but I don't have OZs.

Hope that's of some help to you.

Mine had the following on amil gottis:
Rear: Toyo T1-R 235/50ZR16
Front: Toyo T1-R 205/55R15

Mine has amil gottis with 205 x 55 x 15 (F) & 225 x 50 x 16 (R)

just thought i'd bump this thread as i need to know what's the biggest 888's you can fit too oz split rims, i have done a thorough search but can't find the answer.

[steve-V8s]

If you go to the Toyo web site and look at the R888 data it will list the optimum and allowable rim sizes for each width. First however you need to know how wide the rims are. As suggested the original rims do normally seem to be 7 inch fronts and 7.5 rears.

[Hoover.]

Find out what the width the estorils are, if they are the same as the oz's then you have your answer above

[tbdgriff500]

i have been reliably informed that a good correct size is 245x45x16's on the back with 225x50x15's on the front which should keep the original stance.
can't wait to get them on the car, fresh rubber and newly refurbed oz's, altogether not going to be cheap but worth it in the long run, as i would not be happy with a compromise on rim choice for the sake of a couple of hundred quid!!

[leerdam23]

ok, so what brand tyres then. I'm thinking Hankook RS2 on a value for money basis and predominantly dry road use and track days... anyone had any experience of these?

[LordGrover]

Toyo T1-R if road only. Try R888s if any track use.

[tbdgriff500]

i have found 888's excellent in the wet when new even with standing water but once half worn can become lethal with standing water and need warming to get good grip in wet conditions wich can be hard to do.

[leerdam23]

I'm not sure I want to put 888's on it. So, tyre choice seems to be (as I have 15" fronts)

Toyo R1R or Hankook RS2

reason being I want some wet weather ability, ie if touring and the heavens open up but also some track action etc. I'm quite familiar with the 888's and would defo recommended them for track days etc but they can get a little tricky on a freshly wet road.

Anyone had any experience of the R1R's or RS2's?

Finally...someone else who speaks the truth about 888's

Don't believe all the hype about being crap in the wet. As long as you have some fairly decent tread depth they are just as good if not better then many other "normal" tyres. If they are worn low then as stated, watch out !

I look at it as a good way to keep you focused and keep your opposite lock skills honed

If you like to drive hard around corners ( and why wouldn't you ) the benefits you get on a dry road far outweigh any downsides. Those who spend £1000's on shocks and bushes then make do with standard rubber are really missing out

Mind you don't expect too much in the way of longevity

Whatever you do enjoy your pre-cat

In case anyone is interested there is currently a pair of hardly worn 205/55/15 T1R's on Pistonheads TVR classifieds.

They were used for a short season of Sprinting, before being replaced with 888's.

I'v used both the T1R and it's predecessor the T1S, and liked them for road and competitive use.
These would be going on my Griff, but the Griff's Yokohama AVS Sports have plenty of life left in them.

Hi Steve,

Don't suppose you are coming to Gurston Down? It would save us both some bother if you were. I'd like to pick your brains an about the 4.3 too...

Simon,

Gurston is on my list of hills I must do, but unfortunately not this year.

I'll be at Harewood on the Sunday.

Regards
Steve

I've got Hankook R-S2, 205/50-15 front and 225/50-16 rear on my 430. Great performance on dry roads and absolutely acceptable on wet roads. The Hankooks are much cheaper then the 888s, best solution for road & track use i think
