Taking care of Bubbles

I've already decided on the next tires "or shoes" for Bubbles. I did a search on Tire Rack with decending UTQG "treadwear" and with the best price. The results were the same as BAIL OUT indicated. Yokohama Avid TRZ.
Bubbles is very happy about getting his new shoes, but I told him that he needs to wear out his Goodyear LS's first!

![]() Hopefully I'll be picking up the Avid TRZ tires next weekend so I can give you a heads up on any immediate FE change from the LS's. (the temp and my commute shouldn't change that much over a week so any change will probably be due to tires, for good or for ill.) Quote:

In the summer i have high performance tires and 17 inch rims. FE is in the crapper. In the winter i run stock size 15s with Nokian Haka R's. Since purchasing the car i have gotten the best mileage with the winters on.

This is the tire I'll probably go with. Really smooth and quiet ride. Cooper CS4 Touring T (780 AA)

Yesterday I bought a set of the GY Fuelmax tires. These tires say max side wall pressure 51psi. I'll report any noticeable difference over the OEM tires which were GY Eagles. Those ran for 76300 miles exactly and were just getting to the tread wear markers. My average MPG over the life of the tires was 49.8. I kept the tires between 48 and 50 psi. The Eagles were atrocious in the snow but lasted a lot longer than any tires I've ever had on any car.

Ditto, that'll be interesting to see. Do you have a fuel log you can post?

My first impression of the Fuelmax tires is disappointing. I'm comparing them to GY Eagles at the end of their life, pumped up to about 50PSI. The old tires were probably at their best rolling resistance because of their age. The new ones, probably the worst rolling resistance in their life because they're new. It has been cool and windy which makes it hard to judge, but it seems that my glides decay a little more quickly now. The rolling resistance is noticably better when turning. At low speeds the ride feels more precise. At high speeds, probably because of the electric steering and less rolling resistance, I'm feeling more of a tendency to oversteer (or understeer less, I don't know) The squirlyness this car gets at highway speeds when hit with side winds and turbulence seems to be a little worse....but it's hard to tell - it has been windier than usual too.
The tires feel way different and I'm just getting to know them. They may have qualities I may need to learn to take advantage of. |

Rolling resistance seems to have improved a little after about 400 miles.
Impossible to drive a straight line at highway speeds...there is a bias away from straight, pulling left and right. Constantly correcting requires a lot of concentration. It borders on being dangerous. If an alignment doesn't fix it, I will want to return the tires. |

I was out getting an alignment when you posted that....during this past week I tried 32, 42 and 51 PSI. The sidewall says max 51 PSI. Toyota says 32. It was noticeably worse at 51.
The tow-in was way out of spec - was actually a tow out, so the car was always trying to enter a turn. The printout from their alignment jig shows before/after numbers. I haven't taken it out on the interstate yet. |

I know mine is a bit more wander-prone and gust responsive (as well as more responsive generally) with the sidewall maximum pressure in the stock Eagle LS tires.

I don't know if it's because I grew up riding motorcycles and know what side winds can do to you, or if it's because I'm a freak that actually likes running 32psi but I really don't notice strong winds giving me a problem when I'm in the Yaris.

Oh yeah, I'm a longtime cyclist and motorcyclist, too. A Yaris is stable as a rock compared to a two-wheeler. Even with sidewall max pressure.

The tires were fine after alignment. Superior to the OEM Eagle LS in every way. I *think* the main difference as a fuel saver is that they're made to be able to be run safely at higher pressure.The sidewall pressure rating is higher. The rolling resistance seems to be about the same as my old tires were at 32, 45 and 50PSI, except when turning - the new tires are much better. GY's wet dry and snow traction ratings and their "comfort" rating for this tire are much better than those they give for the Eagle LS. I concur that they're smoother and quieter, and the handling, especially in curves, is a lot better.
