I didn't have any problem with wander at all.
Take you hands off the wheel & it still tracks great.

It's hard to read toe on some printouts.
Some systems give measurement in deviation, then a total toe.
My total toe up front is 0.02
total toe rear is 0.17

Thrust angle -0.01 <---- this one is important


:edit: pic removed .... wrong one

 

Your tires tell me your alignment is way off. Your
cutting the inside of your tires (as you can tell)
Where ever you had your alignment done hasn't had
there rack calibrated. Thrust should be set at 0.00!
Take your car somewhere else before you destroy
those valued winter shoes!

 

Thanks Ian. Good to hear there is no wander at all with that little toe. Do you know about the camber? I'm was planning on taking mine in this week but think I'll just wait until spring to get it done. Mine is out for use now because I never had it aligned after my accident and they had to straighten frame I think like 8mm. The wear I'm seeing on the one front is undoubtably due to that. Car tracks and steers perfectly ever since though.

Yes my dealer printout gives OE specs, deviation and totals.

Total toe -

front (.00 - .08) actual .07

rear (.00 - .22) actual .08

Camber

front (-1.25 - .25) actual -.89 & ? ) diff. .42? printout messed up

rear (-2.00 - -1.00) actual -1.91 & 1.88 diff. .03

 

I played with a few different settings when I had Eibachs & camber arms
JMO, but I'd say there's too much toe up front & too little out back.
I have found that ~0.1 to 0.15 more in the rear than front works well.

 

Sounds like something worth discussing with my shop and trying out. They're pretty obliging so I'll change up the settings a bit next spring. That's a pretty big change on the ratio of front to rear compared to where I'm at now. I checked and thrust angle is +0.01 not -0.01

I'm curious to know how much settings are out now.

Thanks Ian.

 

I'll take a couple of pix of my summers later today,
so you can see how they've worn with this setup

 

Here are some pics of my tires on the car. R. front took a beating at our track. 23.7 k on tires

r. front
l. front
r. rear
l. rear

 

Same here with a toe setting of 0.00 and 0.00. It's nice for tire wear but heck on wandering on the irregularities of the road. Checked my wear pattern on the Pilot Sports and I have a 1/32 more wear on the inside than the outside.

 

Deane, you need to drive that car harder. 24K and that's all the wear you have???? The only concern I can see in the pics, you've id'ed as being from the track. Otherwise, they look really good.

The toe in front, and toe out rear thing is in vogue with manufacturers, moreso than in the past, despite the fact that it has long been recognised as desireable for handling. For an F1 car, it's a must, but it seems that manufacturers feel that we are more willing to tolerate increased wear these days, than in the past.

The worst case of this can be found on the outgoing M3. I remember reading a couple years back a comparo between a c5 Z06, 911, M3 and 350Z in R&T, and the only car that thrashed its tires in their track testing, due to excessing scalloping/feathering, was the M3. Rock stable and great turn-in of course, but hard on tires.

The RE050s have a wear rating of 140, the PS and PS2s- 220. Anything beyond 20K kms is gravy.

 

Derek, good to see you back on the boards.

My pics aren't great and may be a bit deceiving if the tires don't look like the car is driven agressively. I doubt you would get much consensus on that from people who know and have driven with me. Generally I drive normally and then pick my times to really explore safely so it makes up a smaller percentage of hard driving. I've also had 3 alignments done in 15k and with 8k more on am overdue for another now. The rears are past the wear bars - less than 2/32 left in the centres which have worn more than the outsides despite lower pressure of 33-34 (wheels are too small IMO). The fronts still have a bit of life but I had to have them flipped at 13k to even out the inside feathering. The track messed that up however.

Most of the posters here with the 18" PS1 claim to get 20-25K+ miles on their tires so I'm well below that average. I personally have a hard time believing those claims however especially on the rears. There are no treadwear markings on my tires however I'm sure you know what you're talking about. IMHO those ratings are meaningless anyhow. My experience is there is a huge variation between brands since I've had BFGoodrich ZR's with 140 ratings go 50% longer than 220 Bridgestones on the same car. Similliar experiences with other non performance tires of different brands.

Cheers

 

Hey Deane,
On my first G, I managed <20k on the rear tires (dangerous bald at that point), but the fronts were still okay when I sold it with 33k. Subtract about 8k for the time spent on winters, and you're still looking at probably more than 30k on the fronts (and I spent loads of time in the twisties). I ended up going 2 for 1 on rears, and despite my "new car enthusiasm/fanatasism", I was not prone to first gear tire frying. I far more enjoy finding a back road to stoplight-stoplight dragging.

My 050s will be done with 16k, so the PSs did manage to eake out a smidge more mileage, but there are just too many good back roads and a very special set of esses on my way to and from work everyday, so perhaps the comparison is unfair.

Apologies for not making it to your valley race, btw; I ended up having to fly. How has the running been?

 

Good feedback on the tire life Derek. Yeah, you've got some great roads to drive on. We moved into town about 4 years ago, from Fall River. So most of my driving now is in HRM so don't have as much opportunity to be adventurous.

No worries on the Berwick scene. It was a good one with a PB for me and for 3 of my closest running buds. Unfortunately I hurt myself beginning 6 weeks ago - hamstring tendonitis and missed Chicago. My 3 buds all PB'd there. I'm still off but hope to start "jogging" soon. I'm told to expect about 6 months + to heal.

How is the biking going? Let's hope for another light winter so you can have it out a lot, and get an early spring start with the G's.

 

i've also got tire feathering on my car. noticed it when i switched over to my winter's. kind of disappointing.. but what can u do? this is the first car i've ever owned where i've had this problem. i also haven't performed any alignments and i just rolled over 24,000 km. the car's handling and steering act completely fine and normal so i probably won't touch anything till i change my rubber out next spring.

 

Closing in on 5K kms for the season, sans commuting. Bought a new ride (see attached) and amped it to the max (as close to an Enzo without engine as I'll be getting any time soon). Did a pulmonary function test at QEII a week ago to follow-up on last year's lung surgery- things look good. Max HR not bad for a 41 year old (last pic; no duff; repeated at the PFT on their equipment). Just got back from a nice ride. Hard to believe bib and jersey only- no vest, no arm and leg warmers, no booties, no cap, and here we are deep into November. We're doing Hfx-Peggy's Cove this weekend, if the weather is reasonable. A bit of wet, well crappy but tolerable. A lot of rain, mmm, bike and me stay put.

Cheers,
D
