Toyo TR1s or other road 225/50x15 tyres

Sean, what width wheels are you using for these tyres?

If wet grip is important for this set then don't go too wide.

Surely that's as important as other aspects of a tyre.

8x15s front and rear and yes, the thought had occured to me to go more towards 205 than 225 BUT :

that implies a hinger wall profile and even more tendance to flexing
have to admit that wet use will be limited and it's not Wales here after all so dry to damp grip is important too and the L31 will be putting down a reasonable amount of torque !

Road noise is caused by....the shock of air being squashed against the tarmac.

Quieter road surfaces are simply created by 'producing' more space on the surface for that air to dissipate under the tyre.
A tyre with less flat surface arear with already be dissipating that air before contact with the road surface....hence a wet tyre should be quieter in theory than a semi-slick.

Since my rebuild is leaning more towards being a GT and less of a road-warrior/track-day car, I'm looking for a complimentary tyre.

I'm running 205/60s on 7 inch rims on the Z and on the 911 with 8s on the rear a 215/60

If you want the bigger choice then you need to go to the 205 width, but at the minute I think you are looking for something that doesn't exist. Don't be fixated by sidewall stiffness, a trick in the rain is to stick a few extra psi into the tyre anyway, as it helps keep the tread pattern open to dissipate water and also gives increased sidewall stability. Will your touring suspension set-up be able to deal with a stiffer sidewall?
So I would suggest having a re-evaluation of your actual needs and resulting requirements
Hope that doesn't sound harsh, it's not meant to be ;)

Not at all Mike - all good feedback and sometimes one cannot see the wood for the trees - getting fixed sighted on something, it needs another pair (or pairs) of eyes to find a solution.

Fact 1 : mostly to be driven in the dry
Desire 1 : able to handle wet roads well

Car will be low, really low on complimentary spring rates and adjustable shocks on coilovers

I was looking at those tyres with reinforced walls to prevent curbing damage - they have an even worse wet rating so maybe by deduction, some flex is desirable......?

I run a set of T1rs on my Mr2. They are a cracking tyre in the wet and quiet due to the slightly softer side walls.
They replaced a set of Bridgestones which were stiffer in the sidewall and therefore quite noisy but, had a sharper on turn in when dry.

The T1rs are pretty cheap and ok for a daily driver imo, but are a compromise for dry performance.
Ok for an old Mr2 with tired suspension but I wouldn't put them on a performance car.

Thanks.

For dry performance, I'll have the R888s......you're beginning to convince me back to the T1Rs......

Do you know why Toyota badged the MR2 only as an MR here in France ?

888's all the way for dry performance but, I thought you were after a daily driver tyre?

No idea on the MR, 2 front?

Yes I am.

I have 2x sets of wheels and will have one set fitted with R888s for serious dry weather piddling. The other will be daily tyres....I saw how quickly my 888s wore out just 'daily-driving' so I want to preserve them for their natural habitat.

MR2 is pronounced in French : 'Emm uh der' which is exactly how 'we' prononce the descriptive word :

'emmerdeur' which translates as someone who is a pain in the a*se/pain in the neck !

Not quite what Toyota France wanted to commercialise !:eek:

I always thought it was too close to merde for comfort.
Is an emmerdeur literally someone who does merde?

Sean, if you are going to scare yourself that much, then you best get some panty liners as well :)

They're all sorts of solutions to avoid such a mess but luckily I don't scare easily:D cheers. Car won't be on the road until Spring anyway I guess.........:eek:

Be interested to hear what you think of the tires as I will be looking for some purely road tires.

My spell check never like tyres and I can't spell to save my life so what hope have I got.

Several months!!! Your new tyres will have started to go off by then. My R888's are noticeably poor after 1 year but by that time they are true slicks anyway so should be replaced.

Yeah - US spell checkers have a lot to answer for.

Spring = just 3 months - need 'em on the wheels anyway to set up the suspension and corner-weight the car.

My old R888s lasted me 4 years and then another 18months on another car after I sold them on.
