Excited?

¨Excited?¨

There tires man , not a supermodel.

When I was buying tires a couple of weeks ago I could of gotten those. But my car spinning out in the rain and crashing is not worth the 1-2mpg benefit. They have the same traction qualities as Kelly tires.

I take it they are considered LRR tires? They came on my Yaris Hatchback as original equipment.

Cars don't spin out in the rain and crash. Drivers spin out in the rain and crash (with very rare exceptions).

Enjoy the tires, Formula!

I have read reviews about bad rain traction. But honestly, the falken ze512s werent that great either. So I can not argue that point because i have no experience with it yet. Thank you for your concern.

Onegammyleg, They may be as thin as supermodels. that is for sure.
I think if i could find a supermodel for $200 i would probably ride on her instead.

thanks metro!

:eek:

Hey, the man would only be doing what is rational. :cool:

i concur

I haven't spun out yet. Maybe im just lucky, or maybe those who report such incedents drive like idiots.

If you are going to spend the money on LRR tires, be sure to look at other (often overlooked) aspects of rolling drag.

For example, brakes that aren't in very good condition can stick a little bit. And when this effect isn't large, people tend to ignore it, as the engine can easily overpower the small drag. But that drag is real, and it saps FE. Which is why I recently had my independent mechanic do a GOOD QUALITY "brake job" on my car. Unlike the fast chains, he didn't do the quickest/cheapest/easiest brake job. He carefully unstuck everything, adjusted everything properly, and lubed up all the "sliders" (on the front disk brakes) and springs (on the rear drum brakes). And since the front pads (that had been put on by Midas only 2 years before) were now almost shot (both due to the poorer quality of the Midas supplied pads, and the sticking in the sliders), he put on higher quality pads in the front (the rear pads still had about 1/2 of their life left in them). Not only should this brake job help FE, but I suspect this brake job to last a lot longer than Midas's did (both due to the higher quality pads, and also the lower brake sticking resulting in less brake wear)!

NOTE: We would have changed the brake fluid, with fresh (reasonably high quality) brake fluid at that time. However, it didn't make a lot of sense, as we had already flushed the brake fluid (and replaced it with this stuff: https://www.valvoline.com/pages/produ...asp?product=51 ) a month or two before (so the brake fluid was nice and fresh already). However, if I hadn't so recently replaced the brake fluid, we would have done that as well (as brake fluid is cheap to replace, and old brake fluid can make the brakes work much worse than they really should)...

And my car is around 15 years old, and supposedly has "sealed bearings" that you can't lube up. And while we haven't yet figured out how to get around that limitation in the front wheels, in the back wheels we were able to drill/tap a small hole in the wheel center, and screw in a standard grease fitting. We then squirted in some high quality (full synthetic Amsoil) grease, into those fittings. It worked so well, that the mechanic said it had been around 20 years since the last time he saw wheels turn that easily!

The two mods (above) made a HUGE difference in my "coasting" distance/ease. In fact, until I started coasting more in 5th gear (instead of neutral) when approaching a light, I actually had to use my brakes MORE, as I just didn't slow down "fast enough" when coasting! And even when I'm driving normally, I suspect this lower "rolling resistance" (due to having wheels that spin more freely) is helping FE.

So congrats on your LRR tires. But if you haven't already done a good job of checking your brakes (to make sure they aren't dragging, even a little), and greasing up your wheel bearings (with the best quality grease you can get your hands on), I would look into those two areas as well. Because better spinning wheels can make a huge difference (my guess would be a much more noticeable difference that LRR tires)...

AWESOME!! you should definitely make a separate thread for this!!

Along the lines of what Draco mentioned every 5k when rotating the tires (ya I am crazy) I make sure they spin free, just give them a good roll and see what they do. They don't roll as good as you might think, but I know how they roll now and can see if a brake is sticking or something else might be wrong. Just another little thing to check.

In my experience I have found in front wheel drive cars the front tires tend to wear out faster then the rears, which makes since because the front wheels are carrying the majority of the cars weight and they do all the turning and pulling. I agree though that having a good alignment is very important. I also do a 5 wheel rotation, the spare is the same as my regular tires so I rotate it though so they all have pretty even wear and then if I ever get a flat it will match ;) Anal I know... I also figured if I have a matching spare I might as well use it.

Well sometimes they do a 4-wheel drift, but I think the better course of valor is slowing down (which you're probably doing anyway).

Yeah brakes and wheel bearings are often overlooked.

When i first got this car the wheel bearings were shot and eating up my tires, making horrible "wobbling/ humming" sounds when i would take turns.

Replacing the rear bearings was not hard at all. Probably one of the easiest things I have ever done to a car.

It is funny you mention brakes Draco. I am in desperate need of new front calipers...
THe guy who had the car before me did not exactly take care of it.
The first time i went in to change the brakes the front calipers were locked down due to noone greasing them, It had completely wore out a new set of pads in about 2 months.

I had to take a hammer and beat the caliper to get it to slide off the pin.

Anyways, they arent locked up(the way they used to be) but I still feel that i need to replace them. When i relubed them, they were still somewhat hard to "slide"
