Default What street rubber offers the most "stick"

Last year I upgraded from 16" to 18" Porsche sport design ten spoke 996/boxter wheels on my 944 S2 Cab. the car is now a turbo.

Remember the S2 had narrower wheels then the turbo.

Was running 8 inch rear with a 52 offset with 225/50/16

Now running

front tires.....8x18...et 52...225/40/18
rear tires....10x18...et 65...285/30/18

Since the change the car seemed to feel a lot less nimble, less road feel & less dead center thru the steering, it feels find of "propped up" as if it is riding or supported by a wider base especially in the rear almost truck like. I know there is a "lot more" wheel inside the rear, Granted the rubber on these was a little old but not warn.

All the shops I speak with claim size wise this is a std upgrade to a turbo, two sizes up for the S2. Could the 4" wider rears with the offset throw off the geomtry? Was running spacers in the front but in switching to Turbo "S" spindles no spacers now.

Not sure if I should buy new tires or go to narrower rims? Also what is the stickiest road tire?

Thanks

There is no single "stickiest tire". High-performance tires have different characteristics, such as turn-in response, road feel, cornering grip, braking grip, etc, in varying degrees.

Overall...the "stickiest" tires you can use on the road would be Yokohama Advan A048s and Michelin Pilot Sport Cups. Most people don't like to use them on the road because their wet grip and treadwear ratings suck. Some people are okay with that. A few cars actually come with these, OEM, but only bat**** crazy cars like Lotuses. I used to run A032Rs as a dual-purpose street/wet track tire. Great tires, lots of fun, but if you live in an area with lots of rain, go with Goodyear Eagle F1 GS-D3s instead.

Thanks,

I have driven with cups on the street and my RS has a variation of them. I keep the car in Fla so warm up is easier. What about the "Porsche" designation?

This is what I run on my 951. Got to test them on a friends car first. Great tire and decent pricing.

Dunlop Specs are great for street/track use. 200 treadwear,sticky on the track, great in the rain and cost effective.

If you're in Florida and are prepared to use R spec (which will wear faster than street tyres)then definitely consider Nitto NT01. Very sticky in my opinion.

So many great tires for us. You won't go wrong with any of what has been posted. Pick what you like. Discount Tire will match any add from Tire Rack. Just bring it in, and they will match that price. Great folks to deal with and they will install them immediately if they are in stock.

Everyone else has covered the "stickiest tire" effectively I think so I'll address why the car feels more "dead."

It's very much about the increase in weight of the wheel/tire combo that is causing the change in steering feel and nimbleness. The truck feeling in the rear I suspect has more to do with alignment although it will ride rougher as well due to the increase in unsprung mass.

Well said. Who cares what is the stickiest tire now, he is having stability issues. Thank you for addressing this., first...

Yes I mention tires cause a few shops said that might be the cause, but I do not think so. But again isnt this a real common upgrade?

I wouldn't call it common.

More importantly, common doesn't mean it is a change that doesn't have side effects. A lot of people on this and other boards don't care about or don't notice what you're experiencing when they do this kind of change.

I'll guess your current setup is >55lbs per corner in front (stock is ~45lbs) and the rears >60lbs (stock rear was also ~45lbs).

The answer is a lighter wheel/tire combo (and most likely an alignment), live with it, or go back to the stock wheels/tire.
