My original Yokohama avid s33 is about ready to be changed. It now have over 42k on them. I think I can still stretch it before the winter starts. My OEM size are 195/65/15 and I'm thinking of getting the 205/65/15. According to Tire Dimensions Made Simple - Discount Tire my tire rotation will decrease by over 16 revs per mile. I know the side wall is going to be about a quarter an inch higher about an inch and a half bigger in circumference And the car is going to sit half an inch higher and a wider Witdh. Have anyone done this to their Prius and what are your observation/s pertaining to performance, mpg, handling, traction, etc.
I can't suggest anything without knowing your motives. If you need ground clearance then the 205/65/15 will give it to you. If you want better handling then the 205/60/15 will give it to you. Either one will change your speedometer reading.
I'm trying to get the best mileage and handling out of my tire. Looking at the discount tire's web site your actual speed changes as you change your tire size so I was assuming that it might correct the 2mpg discrepancy on the actual and speedometer mpg if I change it. Or does your speed have nothing to do with your mpg?
Speed has everything to do with your fuel economy but if you change your tire size to a larger tire to fix the 2mph speedo error then you will start driving 2mph faster than you used to which will result in lower fuel economy. That is if you continue to just set your cruise control for 65mph. I found it very difficult to drive at 58mph instead of 60mph after installing larger tires. I knew that, with my OE tires, I was really driving at 58mph when the speedo read 60mph but that was ok. After going to larger tires I just couldn't bring myself to drive with the speedo reading 58mph. Physiological thing I guess.
Just bought a 16 inch rims that came off a Prius V and now wondering what size tire should I buy. 205/55? 205/60? What do you guys suggest for best mileage and handling.
Mileage is a different target than handling. If you optimize one it likely won't optimize the other. Choose which one you prefer and buy tires for that. Then tell us what you find. It's all your choice.
I have gone from 195/55/16 tyres on my UK Prius too 205/55/16 the speedo is more accurate but still over reads by about 2 mph. Handling has greatly improved and with careful choice of tyres my mpg has gone up by about 3 mpg over the OEM tyres. The oddo now under reads by 2.8% but the MFD mpg now shows almost exactly the same as calculated MPG when I add the 2.8% extra miles (covered but not recorded) in the calculation.
No. The CT200h unlike the rest of the nice Lexus cars, uses a 5x100 bolt pattern whereas the Prius v wagon uses a 5x114.3 bolt pattern. The GenII and GenIII Prius use a 5x100 bolt pattern. The CT200h wheels are similar yet quite different than the Prius v wheels.
According to my GPS, my speedometer reads about 2 mph low. Going up in diameter will correct that. On my 05 Wrangler, with the OEM 30" tires (29.5 acutal) my speedo read low and I put on 31's (30.5 actual) and my speedo is right on to my GPS in my phone.
I know this might sound like a dumb question, but how does making a tire wider help fix the odo misread? Wouldn't you have to make the diameter larger to help that? Or am I just not getting somethin. Because that's totally possible. lol
I think the wideness of the tire is almost a happenstance, here, but you would expect larger diameter tires (with shallower sidewalls) to have wider treads. The more critical point is the revolutions per mile (essentially a circumference measurement).
I was trying to get some new rims and tires, but I was't really sure what's best or how to weigh out comparisons between FE, handling, and looks. . .
I think you've already figured out that F8L has done a good bit of research on this question. The first thing he'll ask you is this: Why are you looking to make a change -- what is it that you don't like and/or want to accomplish by making a change? Your answer(s) will guide the whole process. If you are looking simply for higher fuel economy, you'll find that the best thing to do is keep the 15" wheels and get Michelin Energy Saver AS tires. Beyond that, the answers will vary considerably depending on what you are seeking.
