Scooter Posted February 12, 2012 Share Posted February 12, 2012 As said the main thing with tyre pressures is that they are the same each side, if not they can give some squirming and direction changes when coming on or off the throttle. I agree with all the time of the year stuff and also I can't see that normal even good quality road tyres can allow you to get the most from a single. My old stock powered tt's could get entertaining with heavy throttle openings in less than ideal conditions, these singles run double and yet often have the same tyres just a inch or two wider. R888's and the like must be seriously considered IMO on every medium/high powered single build, what's the point of power without traction?

Josh Posted February 12, 2012 Share Posted February 12, 2012 Stock UK is 36 front and rear. I keep mine around 34-36, i try to keep them exactly the same from side to side. With my car being a weekend toy i check them everytime i use it. I go with 34 front and 32 rear and that seems good on the stock wheels and tyre sizes.

Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 Thanks all.. So here's what I will do in this order.. Check tyre pressure (34 to 36) Do a geo setup (Dude I will give you a call) Replace rear tyres (r888's if possible) Go for Syvecs (later this year though or search for a pre-owned one that might come on for sale) I might have to kidnap Jamie to teach me......

Tyson Posted February 12, 2012 Share Posted February 12, 2012 I go with 34 front and 32 rear and that seems good on the stock wheels and tyre sizes. Why would you do that? Apart from increasing tyre wear what are you achieving ? Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2012 Share Posted February 12, 2012 I go with 34 front and 32 rear and that seems good on the stock wheels and tyre sizes. I'll stick with Toyota's spec thanks Quote Link to comment Share on other sites More sharing options...
Chucky_waR Posted February 12, 2012 Author Share Posted February 12, 2012 It does make a little sense having the rears a little less I.e 32.. Does this give the rears a little more flex? Don't they run rears a little flat during a drag session? But then again they are not running low profile tyres.. Quote Link to comment Share on other sites More sharing options...
mellonman Posted February 12, 2012 Share Posted February 12, 2012 i do run mine with a little less then the fronts also, but the fun of having a supra is having the back step out is it not i know it puts a smile on my face Quote Link to comment Share on other sites More sharing options...
Spence Posted February 12, 2012 Share Posted February 12, 2012 I used to have this so you can imagine how I feel about the back end coming out. Lol http://img.tapatalk.com/5ec57fba-b959-fae8.jpg Quote Link to comment Share on other sites More sharing options...

dude Posted February 12, 2012 Share Posted February 12, 2012 Now now lets not be too hasty Dunk if he can back up his choice with results and theory then he might be onto something. Toyotas spec will be for the reccomended tyres and a very normal driving style, just look at bikes, I used to drop at least 6 psi out the tyres for a track day to allow for the fact they will get that much hotter, pressures will also be to optimise wear which we prob arent worried about, but diff tyres will need diff pressures from make to make.

mellonman Posted February 12, 2012 Share Posted February 12, 2012 (edited) now if a tyre wears out quicker what must be happening for it to do that surely there must be more surface contact and a little more play in the tyre = more grip Edited February 12, 2012 by mellonman (see edit history) Quote Link to comment Share on other sites More sharing options...
dude Posted February 12, 2012 Share Posted February 12, 2012 now if a tyre wears out quicker what must be happening for it to do that Not quicker dude, if you set the car like a race car for optimum handling you may run so much +ve rear camber the inner edges will wear and the car may be twitchy hence those settings will be miles from Toyotas designed for a fully laden car driven by the fat family at 60 mph, does that make sense, the more load in the car the higher the pressure, their reccomended will prob be 2 adults and 1 kid with luggage, the adults may be fat yanks.....how many of us do those settings now apply to??

mellonman Posted February 12, 2012 Share Posted February 12, 2012 ...how many of us do those settings now apply to?? ha i doubt that applies to many supra owners at all, any how i have always run a couple less at the rear and not going to change it i like the way it handles / loses grip Quote Link to comment Share on other sites More sharing options...
dude Posted February 12, 2012 Share Posted February 12, 2012 ha i doubt that applies to many supra owners at all, any how i have always run a couple less at the rear and not going to change it i like the way it handles / loses grip Your setting is prob a bit conservative for the way you drive Gary, 30 psi would sound better, sure when you are bimbling around the centre of the tyre will be not quite as hard on the road as with 36 but when you press on and the pres in tyre raises with heat it will sit flat on the road whereas with 36 it will prob raise the edges up reducing the contact patch !!!

Josh Posted February 12, 2012 Share Posted February 12, 2012 Why would you do that? Apart from increasing tyre wear what are you achieving ? I'll stick with Toyota's spec thanks You fellas love a bit of debate and giving a hard time, don't you?! From reading on here, a lot of people seem to run the rear tyres at slightly lower pressure, more than likely for better grip at the rear. Either way, I was just saying what I do.

He said that for standard tyre sizes dude, yes I am aware different size tyres may recommend different pressures. Josh if you read my next reply I said not to be too hasty, not being funny but I wouldn't do something just because other people do it without proven results and or theory to help me understand why they are doing that. Do you understand why you are doing it or are you just taking their word for it? Quote Link to comment Share on other sites More sharing options...
spikedjack Posted February 12, 2012 Share Posted February 12, 2012 Be progressive on the throttle and don't stamp on it mid Corner is my advice Quote Link to comment Share on other sites More sharing options...
ashbuster Posted February 12, 2012 Share Posted February 12, 2012 what pressure should be in ive been putting 36 all around? in 275 / 35 / 18 rears and the back always steps to the right but it needs a geometry setup Quote Link to comment Share on other sites More sharing options...
