Hey guys

i reallyyyyyy hate the potenza on the stock V8 vantage i have its time to change the tires , the top tires here are pzero or the ps2 ? tell me what do u recommend performance , looks ?

the original configuration is 235/403ZR19 IN FRONT
275/30/ZR19 IN THE REAR

I GOT THE STOCK RIMS 19inch 9.5

i wanna widen my rear tires as much as i can for looks and performance
what would be the ideal width while retaining the rims i got .



i fitted a 305 pilot cup semi silks on the same rim and it was fine , but i didnt know if its recommended or not

 

I don't think you can fit 305s on stock rims. Probably 285 max. I have 19x11" rears with 305s and that is a good fit.

As for the tire choice, probably a toss up. I got conti sportcontact 3 which I'm happy with, but I might go with Yokohama R888s or Michellin Cups next for added traction...as long as I don't plan to drive it in the rain.

 

Tires are always a compromise.

I have the Pzero Corsa System on mine. They are good performers but I think I may try something different next time. These are the pretty much DOT legal track tires. The excellent steering response translates to being a bit "dart-y" on uneven streets and rain performance is lacking a bit. I assume you were asking about PS2 "cup" tires, I've never tried PS2's but are probably looking at similar results.

I put Bridgestone Potenza RE-11's on one of my other cars last fall, primarily for the increased rain performance over the Yokohama A048's I had been using. I've been pretty happy with them in the rain and street driving in general. The overall ride quality/performance/price is really quite good.

You might call the Tirerack people, if you get a good salesperson, they can be pretty knowledgeable.

 

On the factory rears I was able to fit Bridgestone Potenzas in 295. I tried fitting a 305 and although we were able to get the tire on the rim we could not get the bead to set.

 

hey guys

well i did fit the 305 semi slick sport cup on a stock 19 / 9.5 rim and i installed it on the car and drove it for a month or 2 then it started raining so i had to change them back to the stock i fitted the 305's sport cup back on the porsche .



am still confused what tire and width should i go for?

 

Well stock tire sizes are recommended from the manufacturer for a reason. Stock sizes are 235 front and 275 rear as you know. You can make an argument for going up one size on each to 245 and 285 but remember that by doing that you are also going to change speedometer calibration unless you also go with a lower aspect ratio. You will probably get a small traction edge over stock but that might be offset by higher weight. In the end, it's probably a wash.

Just because you were able to fit 305s on a 9.5 inch wheel doesn't mean it is a good idea. Recommended wheel width for a 305/30/19 PS2 is 10.5-11.5"...not 9.5. Even if you're able to make it stay on, your performance will suffer because the tire won't fit right. It's silly to put that tire on the stock wheels. The 275s fit 9-10, 285s fit 9.5-10.5, and 295s fit 10-11...so 285 is probably the widest you'd want to go on a stock rear wheel.

You can go with a wider wheel and it will fit...I've heard of up to 12" width fitting on this car... but with a stock engine the only point of doing that is for aesthetics. The stock power of the car isn't enough to need tires that size, and you will make your car slower by putting a larger heavier wheel/tire on the rear. I went with the 305s on 11" wide wheels because my car is supercharged and I wasn't getting traction in first and second gears.

So the question is...do you want it for looks only or are you going for a performance advantage? Going wider than stock on a stock wheel won't necessarily give you better performance and may hurt. Don't do 305s on stock wheels. If you want to improve performance go with lighter aftermarket wheels and appropriate tires to lighten unsprung weight, but don't go wider than you need...stock engine on a 2007 doesn't need more than 285 in the back for good traction off the line and I really think the 275 was enough when my car was stock.

How's that?

 

thats great write up

well i was experimenting with the 305'd .

but am not an expert in tires so thats why i posted this thread looking for and advice

:-)

 

If you are referring to street tires and not track type like the Michelin PS2 cup....I would consider Hankook Ventus v12 evo if you are looking for value and performance versus just a name. These tires outperformed Michelin PS2's in a tire comparison as well as other top brands (Bridgestone included) in C&D (or R&T) magazine not too many months ago. The savings is great and the performance spoke for itself in the shootout. As far as sizing, in the owners man. of my '09 it lists a performance option tire size with 285 being the rear width instead of the 275 re050's it came with.

 

Be cautious that the rosso's are a terrific tire but "large" for their size, . I had a set of 315's on my old car that were almost and inch wider, shoulder to shoulder, than my hankooks which were also a 315. not all tires are created equal.

 

thanx for the info people ohh by the way whats up with the new pirellis trofeo looks so tempting

 

Another thing.

I bought my Corsas from my dealer. According to him the tires are a "special build" for AM. They were not more expensive than Tirerack btw. It was a year ago and Front tires were $493.99 each, rear tires $556.88 each.

AM sent my dealer this:

The following information has been supplied by our Vehicle Dynamics Engineering Team and clearly explains the advantages of using genuine AML tyres.

‘The recommended tyre fitments for Aston Martin vehicles are the result of a significant amount of testing and development. As a result of this all of our tyres are unique in construction and compound and optimised for all aspects of road performance on the vehicle. These unique specifications are marked by the inclusion of Aston Martin unique identifiers on the tyre sidewalls (AM9 for DB9/V8 19” Bridgestone tyres, AM8 for V8 18” and AM/L for the Yokohama tyres for Vanquish).

During development the tyre performance is tuned in unison with the chassis to optimize the balance of the vehicle in steady state and extreme manoeuvres, give excellent steering feel and response, a balanced ride response, have an optimal compromise between wet and dry grip and, at the limits of adhesion, to be predictable and give excellent feedback to the driver. At the same time the NVH (Noise, Vibration and Harshness) characteristics of the tyres are considered; (airborne) pattern noise, cavity noise, rumble, impact harshness and steering corruption.

Aftermarket tyres by comparison will be further compromised in their performance by being tuned to a range of vehicles. A tyre offered in the aftermarket must be tuned to give safe, predictable handling on a wide range of vehicles that might use a particular size of tyre. As a result aftermarket tyres are likely to be less responsive, may have different dry/wet characteristics, may have a poor ride balance and specific NVH issues.

Compounding this is the fact that our product range has different size front and rear tyres. Fitting aftermarket tyres would mean mixing specifications of aftermarket tyre and thereby altering the handling balance and ride attributes of the vehicle’

I hope this clarifies the situation and the clear benefits in owners fitting genuine tyres to their cars to protect handling and ride characteristics as well as high speed safety and stability.

The unique nature of genuine Aston Martin tyres means that they are more expensive than an aftermarket equivalent, however we constantly benchmark our tyre prices to remain as competitive as possible.

 

Maybe I'm too cynical, but I can't help but think the reality is that Aston just would like to sell us "tyres."

 

I agree with you. I can see their choice of sizes, but the idea that they used a special compound and other features ideal for this particular car and that all others just won't work is nothing more than marketing mumbo jumbo.

 

i agree

 

Throw some spacers on the back to widen the track and fill-in the wheel wells, then slap a set of Hankook Ventus V12's in 285 out back and 245 up front. Wider, stickier and less expensive than the Bridgy's it came with. And once again, no, 305's are not a good idea on the OEM wheel.... Send some picks when you're done.
