Toyo T1-Rs

Hey bigdog, what tyre pressure are running on yours?...my know-how tyre fitter recons for this size....44psi is best....what do you recon?

[Okibi]

I run about 32psi in the 15\" T1-Rs on our NB8A

[bigdog]

It will ride like a cart at anything over 40psi. I run 30 all round cold, goes up to 32-34 hot. Side walls are very narrow so they don't roll around much at normal driving speeds. I would run 36 hot on the track... but these haven't made it there yet.

[fleery]

Was just about to ask the same question! As you know, I just had mine fitted. I took them through the paces through some twisty backroads and found them very squishy on the sidewalls at high speed through corners.....even a little scary! Have them fitted to standard 16\" NB8B rims (205/45/16). Tyre guy recommended 36PSi front/rear. I tried 38PSI for the return trip and they seemed a little better, but still dont feel as good as my old warn out Turanzas!

Any suggestions!! Maybe have them too hard! What are people running at the track??

Thanks

[bigdog]

interesting Fleery. I have fairly stiff suspension - Konis and Kings on mine, and they are certainly not 'squishy' at 30 psi. I wonder if you are actually going a bit quicker than the Turanzas allowed and feeling either inadequate or worn stock suspension?

[fleery]

Yea, that could be an explanation for it. They definately do stick a lot better on the rear than the Turanzas. However, if you are at around 100-120 and turn in quick, it seems that there is a slight delay for the rear tyres to catch up to the front - giving the 'boat like feeling'!!

Are the made in Japan ones with a build of XX06? (XX = the week out of 52 that they were made btw). Mine dont seem to have the problem but I did get a nasty wheel alighment done at the time!

[fleery]

Hmmmm...Ill have a look at the tyres when I return from OS in about a week!

[Craig]

OS eh? Want me wander over and warm up the engine and take it for a run to charge the battery?

[fleery]

He he he....

Just put a set of T1-Rs on the NC.

I procrastinated about them or the Michelin PP2s. There was absolutely no difference in price - $250 a corner. In the end I decided to go the Toyos hoping they would last better with the odd track day that I do. Mind you the PP1s lasted 30K plus 6 track days so they were pretty good.

After just a week on them I’ve found that they are softer in ride than the OEM Michelin PP1s. They are just as quite, but and it is a big BUT, they seem sloppy.
I know that people will say wait till the mould release is worn off but this isn’t slipperiness it’s slow reaction to steering inputs.

I’m running 32psi, 10% higher than the recommended pressure, so if I go higher I will be trading off grip for response.

I’ve yet to really try out the grip so I’ll reserve my final opinion till after I really break then in at Wakefield in March.

Fingers crossed that they hang on better than the Michelins otherwise it’s an expensive mistake.

CB, I found the same thing when I first got my tyres. They weren't overly slippery to start with but the were very squishy with their response. This seems to have gone away to a major extent with a few good runs on them.

I have taken some good fun runs on them but I look forward to giving them an absolute thrashing somewhere to see it they firm up even more.

BTW I'm running 36psi cold. Haven't played around with pressures yet but when I'm feeling a bit less lazy I might get out and do it.

[fleery]

Mine seem to be a bit better, I now have them at 34PSI instead of the recommended 36PSI. But I havent had them up at high speed again yet.

Craig - had a look at the tyres and I cant find the code you were talking about...all I found was a 'made in japan'.....the Dot rating DOTCXVN, code PXT1R and the following which I have no idea of....0225321 and 0225510-S...

Fleery.

Made in Japan is the important one, means they aren't the crap imports from China. The date is a 4 digit number on the tyres sidewall, from memory it flat and oval where the numbers are, not hugely important unless they were old stock but I doubt that as most tyre place ran out as Toyo didn't order enough for the anticipated demand last year!
