Pardon me if this has been answered somewhere on the site, but I didn't have much luck turning up an answer. Lots of posts addressing +1, +2 and even +3 rims. . . When the Goodyear Integrity tires come off the stock rims for studded snow tires this winter, I was considering going to aftermarket wheels and tires the following spring. Unfortunately, it doesn't appear that the favorite all season tires -- Goodyear Comfortreds or Tripletreds, or Michelin HydroEdge tires come in 195/55 16" sizes. Will 205/55 16" tires safely fit the 05 Prius? Thanks for the help, Steve Zettel near Libby, MT USA
Really? that's interesting Well, they may fit but note that because they're wider, they may rub against the inside of the fender. Avoid full locks.
What is your source? I am not sure if it was Goodyear, but I have heard that the web had bad information for a tire manufacturer. In other words the manufacturer's site didn't list the Prius for that tire, but they had the size.
Discount Tire (www.tires.com) has that size listed as an option. They seemed more willing than other big retailers to consider alternate sizes, when I was shopping for tires.
<div class='quotetop'>QUOTE(DanMan32\";p=\"90286)</div> Hi Dan, Neither the Goodyear site nor the TireRack.com site have a ComfortTred or TripleTred listed in 195/55 16" Steve
<div class='quotetop'>QUOTE(gschoen\";p=\"90304)</div> Interesting. I just did a series of searches at Discount Direct online (I was referred there by the site since I am more than 100 miles from the nearest store) -- the *only* hit was for a Dunlop tire, and that was in 195/50/16. Thanks for the pointer though -- my alternate plan will probably be to go with TripleTreds in 190/60/15 and lightweight aftermarket wheels. Cheaper, too. Steve
You can save weight, gain contact patch area and improve performance (at the expense of fuel economy) by careful tire selection. Compare specs at the Tire Rack site. I've run Bridgestone Potenza RE-950's and Goodyear Triple Treds, both in 195/60HR-15 size. No rub at all. Both are heavy, but with the overall smaller diameter than OEM compensate by lower effective final drive. My butt dyno says they accelerate better than stock, and in the case of the Potenzas, change Prius towards a sports sedan. For my '06, I'm considering the Yokohama Advan AVS db ultra high performance all-season tire in 205/60-15 size that will fit on the stock rim, if the size is still available this November. Tire Rack told me that 205/60 will rub slightly at full lock, so some mods might be in order. The Advan is a superlight tire in that size, about the same as the OEM tire.
Where did 195/60R15 come from? My Goodyear dealer priced those for me in TripleTreds, and when I 'corrected' him to 195/65R15 like www.tires.com said, it ended up saving me $6 per tire. So the chart says: What chart says 195/60R15 will not change reported mileage (or whatever else a total diameter change will do)?...
Size came from the dealer. They've been on my car since Day 1. I don't understand your chart question. The TT's did reduce fuel economy slightly, but nowhere near as much as the Potenzas in the same size. I've posted previously about my experience with both here.
My question is about tire size changes: http://www.miata.net/garage/tirecalc.html Tire Size Comparison Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 185/65-15 4.7in 12.2in 24.5in 76.9in 824 0.0% 195/60-15 4.6in 12.1in 24.2in 76.1in 833 -1.0% Tire Size Comparison Specification Sidewall Radius Diameter Circumference Revs/Mile Difference 185/65-15 4.7in 12.2in 24.5in 76.9in 824 0.0% 195/65-15 5.0in 12.5in 25.0in 78.5in 807 2.1% When www.tires.com said use 195/65, I assumed it was the correct thing to do. Now looking at the results of this calculator, I can't tell what I should have done...
Go to Tire Rack's site and compare revs/mile between brands. For any given size, rpm's tend vary between brands. That played a part in my decision in choosing a smaller diameter, lighter, all-season HR rated tire. Improved acceleration and grip were priorities over fuel economy.
