overall, i think a push in set up, is a good thing for novices. very hard to get in trouble, but generally, when the car gets to this level of grip, even with a stock suspension, its still very balanced.
this driver, has some track experience too, and handles the car quite well and has a good head on his shoulders. i wouldnt give him a worry! )
generallly, the 928 is a pretty good mess with stock sized tires on it good for 1980, but by todays standard, i challenge you to find a 3600lb supercar that has 225s on all 4 corners. it wasnt designed that way, it just was the thing to do back in 1980. the car has good balance , decent power and needs a stagared tire size set up to be safe in my opinion, and it certainly helps its performance, both street and track a car with this weight , width and power, has no problem fitting 305s on the rear, mated to what ever can be fit up front

So, junk up front (zeons) and temperature and pressure temperamental dot race out back that will dry our before wearing out?

Who's idea was this?

Aww c'mon.. everyone knows that putting racing tyres on the rear only, means the back will go faster than the front

Speedtoys gets dibs on the ToldYaSo dance if the OP spins.

I am guessing that this is just a transition thing, not THE plan.

R888 are not a tire I would give to a novice, especially on a colder day!
A guy like me needs the grip for better safety

Petty. Whoever told you that, or allows you to continue thinking that, needs a talking to.




You'll be a GOOD driver at about age 23, if you start getting good advice now.

You're not.


You can't buy experience, even if you've been handed all the tools to get it with for free.

No offence meant, but better grip means the car will go MUCH MUCH faster before it lets go. A novice is best on small hard tires so that it lets go early. This way they learn at a slower speed where the consequences are not nearly as dangerous.

Its like sticking a novice in F1 versus class F.

My view is unless you are on the race track or drive an upgraded car then the stock wheels and tires sizes give you the best combination of grip, traction and ride comfort. The car handles and rides perfectly well in all conditions with the stock setup at well above normal road speeds that you would encounter in the US.

Other reasons to go big are either are that you can't get the correct sized tires or just like the look of big wheels and wide tires.

I hope you don't really believe that. Grip ... and lack of ... can get you into very deep **** very quickly, and you'll just be a passenger.

Please take good advice on tire choice.

I think wide tires are a nice update on any street 928. I have 295's on the rear and for street driving I do not see any difference except at slow speeds in ruts. Down the highway it feels perfect. As for tracking the car I have no experiance so I rely on others that do. Is this kid tracking the car anyway? I don't see where he said that but maybe I missed it.

Are you familiar with driving in the US? And if so can you please share with us any notable differences in speed limits? Also how would you rate the roads over there? I would imagine desert driving would be much the same as in the desert SW here. Are the city streets really good, really bad or somwhere in between? I would love to see it for my self but anything you can share would be much appreciated.

Look, you guys are over thinking this. race rubber, street rubber, DOT, not dot, its friggen tire. ive proved many times that anything you can do on the street doesnt hold a candle to what is done on the track. remember my tests going up hyway 9 with my first test of the large hoosiers and susension set up???? worked great. on the track, it lasted one lap before the tires came off the rim , literally !
point is, if its not raining, put what ever on the car you want and you will never get in trouble. drive like a normal person, not like someone on crack, and you will never get in trouble.
ive driven with Ricky, and he has some track experience too. Good common sense.

Now, race rubber in the rear, crappy tires up front. whats going to happen??? ive driven the car, its the same as a car with brand new michelins. i have the luxury of jumping in one and then in the other and run on a track like condition every day. ask ricky! sure the cars are subtly different at the edge of adhesion, but, nothing that phased me too much. to me, they are just street cars. slow and sloppy .
one has 6 liter stroker with the bilstiens and eibachs and the other is bone stock, but in very good shape.

dont over think it, and dont post FUD where there is no basis for your suggestions. instead, get to the track and improve your skill sets so that if you DO get in an emergency situation you can get yourself out of it, regardless of your tire brands and tread depth.

by the way, ive logged 50,000mile on DOT tires and they wear out (street or track) when dry out at about the same time, IMHO.

R888s are basicallly just a sticky street tire. for a low mileage driving, 928, its a great tire

true in some ways, but I dont totally agree.
actually, the sticky DOTs give a LOT of feedback, especially when cold, and to your point, might even have less grip than a street tire at cold temps. so, that assesment is REALLY depenedent.

again, its a tire. I can get in any car and make it push, make it slide, make it wiggle. Its all driving style and finding the limits in all attitudes. pretty easy to figure out in a corner or two..
