Hi everyone:)<br> I know that tire size has been discussed many times in the forum, so I am sorry if I am repeating an already answered question. I am ready to have my snow tires swapped for summer tires and wanted to go up in size. I have decided not to go up to 18", although I love the Medeas, and was wondering what size I could go to on my existing 17" sculptors. <br> I have lowered the car with the Heico springs, which definately improved the handling and got rid of the SUV like look of my awd s40, but I still feel that the tires could be wider. Any suggestions? Thanks. I appreciate all of the great posts. You all have been extremely helpful. <br>-Bobby<p>S40 t5 awd 6mt<br>dynamic trim<br>Heico springs<br>k&N filter

Re: Tire size (rcy4499)

For the rim width of 7":<br>225/45/17<br>215/45/17 <- difficult to find the proper load rating in this size.

Re: Tire size (slo-vo)

225/45/17 should be better. But consider a ridiculous case with really wide tire on really narrow rim. The tire would bulge out, making the sidewall flex more. So then the handling advantage of going wider goes away, or at least is not as good.<p>Going wider in tire is better on a wider wheel. Unfortunately, no one makes a 17x7.5 or 17x8 wheel with our 52.5 mm offset. Personally, I'm going to go with 225/45/17 also, but on a Pegasus 17x8 Volvo wheel with 46 mm offset. I haven't actually done this yet, and will complete a posting or two on swedespeed when I finally do it (there is a complication having to do with hubcentric rings).<p>tirerack.com has some info concerning tire width and wheel width. For 225/45/17, I believe the recommended wheel widths range from 7 to 8.5 inches. 7 is at the lowest end, which means it has the lowest benefit for that wider tire. 8.5 inches might be wide enough so that the tire does not protect the wheel from curbs!<p>225/45/17 is a good choice because it matches the 205/50/17 overall diameter quite well.<p>

Re: Tire size (bassman)

Have you folks researched which tires? There are probably postings on this too, although I haven't looked myself.<p>I'm going to plunk down the cash to get Goodyear Eagle F1 GS-D3.<br>

Re: Tire size (bassman)

I'm going with 225/45YR17 BFGoodrich g-Force T/A KDW2's soon. I'm expecting a significant transformation in terms of handling and off-the-line performance. Also, since I have the BSR tune I will finally be able to fully put down all the torque I have to the concrete, rather than slip and slide everywhere like I do with these horrible stock tires. Shortly after I get the tires I'm going back to the 1/4 mile strip to video tape my new runs...just need the semester to end before I do all this <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">.

Re: Tire size (bassman)

Michelin Pilot Sport A/S and Pilot Exalto A/S comes in 205/50/17. Avon Tech M550 A/S also has good reviews. Another alternative is Yokohama Advan S.4. It just came out (for this size, at least) and there's no review in Tirerack yet. Anyone had experience with this?<p>Summer tires, maybe GS-D3, KDW2, PZero Rosso.

Re: Tire size (mJrO)

I wish I had experience. I can only spew what I've heard from other sources.<p>I've heard Pirelli tires are either not as sticky and/or on the softer side.<p>tirerack.com has the Goodyear F1 GSD3 tire at the top of the heap (actually the new Dunlop Sport Maxx tire is up there too). <p>Car and Driver (or was it Road and Track?) rated a bunch of max summer performance tires. Pirelli came in as #2!!! But they quickly said why they thought it should not have in terms of actual sport handling. They said Goodyear F1 GSD3 (#1) was awesome in wet, and great but not quite the best in dry. The Bridgestone Potenza (Porsche Boxter tires) were surprisingly not in the top 5 if I remember rightly.<p>Something like Yokohama seems to be the ultimate for dry traction. The Mitsubishi Evo has a Yokohoma tire made especially for the car.<p>I've heard generally good things about Michelin Pilot Sport, although I believe it was also rated not #1 in the tirerack survey.<p><br>For me, only predicting based on what I hear but don't know myself, I suspect Goodyear is better for noise / wear life time / overall wet versus dry / cost in the tradeoff of things. At least for the tradeoffs I'm wanting to make. <p>My other suspicion is this: there are always detractors for every product (many people don't like the V50/S40). And there are always people amazed by their upgrade even if it's not the best. The tire thing to me seems like something where you can gather some info and opinions, but then you just have to try it. That's what I'm going to do with G.E. F1 GSD3. Not everyone agrees it's the best, but by most accounts it seems a safe bet for a high quality upgrade. The others in your list are probably excellent also.<p>Maybe some folks have specific info about the tradeoffs among these high performance tires.<p><br>

I'm looking at Medeas as well... but have seen this info on a few sites:<br>"(18" wheels require steering limiters in the front wheel arches and replacement of "bump rubbers" in the rear wheel arches.)"<p>Anybody running Medeas on their V50? What tire size?

Hey Bassman I realize I have a different car but I run the Goodyears on my vehicle in the warmer months and I've been satisfied with their performance. Certainly an improvement over the Michelin all seasons that were on before. I'm not sure how many miles are on them at this point probably 7000 or so and the wear is good...rotated them once in that time.

i'd go with the Goodyear Eagle...<p>i had these on my last car, which is a modded 01 Eclipse GT, and they felt comfortable, fast, and great on curves, and did a world of difference in overall daily driving.

Re: (Volvo_girl)

I think 7 inches is the narrowest rim for 225/45/17. Stuffing as much tire as possible on a rim does not get the max benefit from that tire. Is 225/45/17 on 17x7 better handling than 205/50/17 on 17x7? I cannot answer that!<p>Tirerack.com has some ASA or Kazera wheels with 48 mm offset that are 17x7.5 if my memory is right (I forget which of the two, maybe both). I think these wheels are reasonable weights (around 22 pounds or so), only 4.5 mm offset difference from our 17x7 Sculptors, and better for 225/45/17. They're pretty afforable. Evolve's R5 also comes in 17x7.5 at 42 mm offset, and is a really good looking wheel with an amazingly great 18 pound weight.<p>My own choice: Shuk W22 wheels at 18.5 pounds, 17x7.5 with 45 mm offset, and of course 225/45/17 tires. I wanted 17x8 wheels, but could not find them from anyone except Ronal (R41) at 22 pounds and 42 mm offset. Also Pegasus comes in 17x8 with 46 mm offset, but the 27 pounds scared me off.<p><br>

Re: (Dygitalpmp)

Thanks for the second thumb up. Indeed, I chose the Goodyear Eagle F1 GS-D3. They're on order. I won't know for another week how they feel...
