Tyre Size for TVR Griffith 430

[scottliv]

Hi all,

I have just become the owner of a Griffith 430 precat. The front tyres have plenty of wear left but have a manufacturing date of 2006 so time for a change. The are currently 205/55 R15 but choices are limited in this size. I have sourced Toyo T1R in 205/50 R15. Obviously these will have a small (20mm) change in diameter. I am not changing the rears.

Does anyone have any experience - good or bad - running these size tyres?

Have a look at the Uniroyal Rainsports, they offer excellent performance and grip. Toyo have been around for a while but there are better options now.

check out the recent tyres thread on the Chimp page - some good info

I have RainSport 5's on my TVR S1 (265bhp Jag engine)

I'd be worried about losing 10mm of ride height. Ain't great in a TVR to begin with.

T1R is an old design of tyre and not great when new. Unless Toyo are re-using model names.

Uniroyal Rainsport for me. The '3' worked just fine and dandy on Tamy and Suni on the road, track, Euro tours, rain and low temps. As far as I can gather from reviews the '5' is an improvement over the '3'.

Uniroyals are good , also Goodyear efficiency grip, Avons still available in 205/5515 if you do go for 205/5015 the choice is greater. Even if the profile is reduced to 50 % of the whith it's only marginal

Hi all - thanks for the replys. I have taken the advise and chosen to go with RainSport 5 at the front with the correct aspect ratio. Didn’t fancy losing 10mm ride height and with wear that could be up to 15mm.

What’s on the rears?

Toyo T1Rs 225/50/16 at the moment and good nick.

OK, only asked as in past have known people mix tyre makes front and back finding it handled like a wet sponge and tramlined , but from memory this was mainly Toyos and Bridgestones, don't know about Rainsports and how they mix.

If you need some man maths to justify swapping the rears to RS5's then check how old they are. Google 'car tyre date codes'. Anything over 5-years then renew.

Once you have scrubbed them in (Rainsports need about 100 miles to get rid of the releasing agent) then you will appreciate the far better handling of the Rainsports. As you bought the car to enjoy it, having much better grip is a price worth paying, so I would agree with the previous poster and go for Rainsports for the rear too.
