October 3, 200718 yr My Mother does not drive her '03 GT legacy sedan very hard at ALL. She does however get it hung-up in snow and high lips on our rural road. What is the thinest/narrowest tires I can put on stock '03 GT wheels? Would 195/60R16's work in place of the 205/55R16's??
October 3, 200718 yr For the difference in circumference its not so much 205/55/16 = 78.2 inch (811 rev per mile) 195/60/16 = 79.2 inch (800 rev per mile) this is a 1.3% difference which can be tolerated Better would be to take 185/60/16 because they are little smaller (77.7 inch) so they will definitly fit. Or you can play yourself at http://www.miata.net/garage/tirecalc.html But they both will fit (195 and the 185) actually winter is comming so smaller tire is more weight per ground area = more grip on slippery surface.

"weight per ground area" is entirely dependent on inflation pressure and has nothing to do with the width. The width of the tire determines the shape of the contact patch, not the size. IMO a 195 or 185 is too narrow for the weight of that car, and you should stick with a 205 section. I don't think you can go much taller before you run into rubbing on the spring perches or fenders. A 205/60-16 would probably work, and snow/mud/offroad oriented tires would also help along with not driving into "high lips." Or she could trade for an outback.
October 3, 200718 yr Author I don't see how weight affects width?? I had a 3 ton truck that had 185/75R15's they were three ply side wall but that was the size. More on tire construction not size. Does anyone know how wide the stock rims are on the '03 GT's.
October 4, 200718 yr "weight per ground area" is entirely dependent on inflation pressure and has nothing to do with the width. The width of the tire determines the shape of the contact patch, not the size. How could choosing a narrower tire not make a narrower contact patch?
October 4, 200718 yr There are a few things that determine the patch shape. Tire tread width, stiffness, tire pressure, and the weight of the vehicle. Your stock wheels are probably 7" wide. Going narrower on the tire is your best bet. If you want to go narrower and higher I would suggest: 195/65R16 or 185/70R16 These would raise your car approximately 3/4" and may be just enough for the snow and lips. It shouldn't be an issue with rubbing anywhere. The stock 195's on my Impreza do great in 11" of snow. 185's would be even better.
October 4, 200718 yr How could choosing a narrower tire not make a narrower contact patch? It is narrower. It's not smaller though if both tires are inflated to the same pressure. If you take two of the same tire, a narrower tire will have a lower load rating usually. Plus with a taller section and narrower tread the tires are going to flex a lot more and it's not going to feel very good while driving.
October 4, 200718 yr It is narrower. It's not smaller though if both tires are inflated to the same pressure. You lost me there ^^^ Just check the load rating of whatever tire you get. If the tire is thinner than the wheel, then the sidewalls will stretch out to meet the wheel. German car tuners do this all the time to quite silly extents. I would not worry about it. Get a nice 185/195 tire that's a little taller like the others have mentioned.
October 4, 200718 yr She does however get it hung-up in snow and high lips on our rural road. This is not a direct answer to your question but may help: 1: Get a set of snow tires in the same size 2: Getting stuck on "high lips" sounds like another way of saying "high-centered". Then you need to buy an Outback or somehow increase the ground clearance on the GT...don't know how you'd do that. Maybe outback struts, springs and shocks in a swap may be the answer.
October 4, 200718 yr Author What do the modded VW's always have the tires too small for the rims? Is there a plus to doing this. Must be hard to keep the wheel lips from geting banged up!!!
October 4, 200718 yr You lost me there ^^^ Say you have a 185 section tire inflated to 30psi and a 225 section tire inflated to 30psi. If the weight on each tire is the same, the 185 will have a narrower and longer contact patch but the actual area in contact with the road will be the same. The 2.5GT wheel is 6.5" wide. If you go to tirerack, you can view the details of a tire and the recommended rim width. For example, here's the sheet for my tires. I have 16x7" wheels, and 225/50-16s. You can see that the recommended rim width for them is 6-8" with 7" being preferred. You can also see that it has a slightly higher load rating than the narrower 205/55-16, which has the same diameter.

October 4, 200718 yr Is there a performance edge from doing this?? no it actually decreases grip and is purely a style thing. A tire works best when the tread width is close to the same as the rim width so the sidewalls are vertical.
October 4, 200718 yr Author Sounds Uber UN-German thing to do!! There engineer neighbors must hate the tuners taht do that!!
October 5, 200718 yr Sounds Uber UN-German thing to do!! There engineer neighbors must hate the tuners taht do that!! The German tuner community, especially the VW/Audi lovers, love to do things purely for looks regardless of the consequences. If you can fit a finger between your tire and the fender your car "looks like a 4x4".

She does NOT want to swap back and forth between snows and all-seasons, I have tried. She does not like the noise and no one is around to load and un-load them from the car. I had a set of 205/55R16 Nokia's for it and she did not like the road noise. Suspension mods are not in the cards, just looking for a cheap fix.
October 5, 200718 yr Going a size narrower isn't going to make much of a difference, especially if the tire is some generic all season. The best solution would be a taller car or dedicated snow tires, and there's not really a magical all season that's going to solve all your problems. I guess you could try a 205/60-16 in a very good all season. Browse tirerack for something that gets good ratings on snow and ice. Additionally, tires that grip better on slippery and loose surfaces have bigger and deeper tread blocks and will make more noise.

So I guess the board is not as hot on the WR's any longer the reported TRUE ALL-season tire? I tried a all-season rated well in loose stuff, the BFG Traction T/A and they wore out in 10,000 miles!!
October 6, 200718 yr What do the modded VW's always have the tires too small for the rims? Is there a plus to doing this. Must be hard to keep the wheel lips from geting banged up!!! You must be talking about the watercooled ones. We aircooled guys like our tires tall and skinny! :cool: - Scott
October 6, 200718 yr Author You must be talking about the watercooled ones. We aircooled guys like our tires tall and skinny! :cool: - Scott Well you air cooled guys have it right, bugs were awsome in the snow. And the Kubel's and Schwimmerwagen's were the first 4wd cars!! I had a '87 Syncro Vanagon with rear air LOCKER from the factory it would climb up a house!! Sorry (wasserboxer)!
October 6, 200718 yr So I guess the board is not as hot on the WR's any longer the reported TRUE ALL-season tire? um, what?
October 6, 200718 yr um, what? Nokian makes an all season tire that's better than a lot of dedicated snows.

I want an old Pinzgauer, too, but that's enough blasphemy from this new member. - Scott
October 6, 200718 yr Author Nokian makes an all season tire that's better than a lot of dedicated snows. OK, cool just checking? I guess the onlt issue with the WR's is the price tag. Anyone have them on there Soob? What kind miles you geting out of these $150+ a PEICE tires??
October 7, 200718 yr I have mounted 205/60/16, same wheels, and no issues, better ride, on uneven pavement
