tyre size

[daren parker]

hello i would like to check if i have the correct tyres on my 4l chim 96 with power steering . rear are 225/55/16 and the front are 205/55/15 thanks

[daren parker]

hi seems tht the 55 should be 50 would that make a difference , looks like 55% of the 225

[That Daddy]

No

205 tyres are generally for pre-cat cars without PAS

205/55/15 fronts
225/50/16 rears
same as mine and standard from the factory (I think)

98 model with PAS

These are the factory recommended sizes. The bible advises 225 50 15 front rather than 205 55 15 but on mine (98 PAS) they catch on the battery box.
I have gone for 205 50 15 front, to lose the beach buggy look and 245 45 16 rear, as I like the extra width.
This may be useful to check the rear size keeps the speedometer accurate. http://www.miata.net/garage/tirecalc.html

The long and short of it is,,,,it makes very little differance 55 or 50 aspect ratio.

Was that Chims? Precat Griffs certainly had 205's if non PAS and 225's if PAS.
Perhaps I should just sod off back to the hairy chest forum - soz

A few different tyre sizes have been fitted, and some different wheels as well. Most depends on your car (age / spec), and subsequently what manufacturers have made available in suitable sizes / ratings / compounds. There are many answers to your question, which most will just claim the tyre brand & sizethey have on their own car is best So in the spirit of things 225x45/16 & 245x45/16 Toyos are best

I agree with Spend - 16s all round with 225/45ZR16s front and 245/45ZR16s rear are a great tyre combination.

Barreti - there weren't any precat Chimaeras - mid 1992 precat Griffiths had 215s on front.

just checked the tyre calculater and a 245 is to wide for the tvr standard wheels , it is called the J ... if you put over size tyres on you can get tyre bulge

[OscarT]

TVR regularly fitted 245s on their new cars - I've been running them for years with no ill effects at all.

Well bugger me
There's me ready to get all upperty that I knew better, so I go get the two '92 precat Griffith handbooks off the shelf, turn to Specifications and right there on page 45 it says
Wheels & Tyres
Front
15" x 7J aluminium alloy wheels fitted with 215 / 50 ZR low profile tyres.
Rear
16" x 7.5J aluminium alloy wheels fitted with 225 / 50 ZR low profile tyres.

I stand corrected OscarT although I did know there were no precat Chimaeras
