Gs300 Sport - Series 1

[BEATTYM]

Greetings all,

I can not get a set of rear tyres to last more than 10K on this model of car. Have tried all sorts; hard, mixed and soft compounds from different manufacturers. Nothing works; the tyres are destroyed on the inner 15% of tread within 10k. I assume its a fault with this model with the wide wheels and lowered suspension. I always have 4 wheel geometry checked after new tyres are fitted. Can anyone confirm this problem and fully explain it or are there GS300 Sport - series 1 owners out there not experiencing this rubber- devouring trait on there cars?

Feedback much appreciated folks.

Marco.

I get roughly 15k out of mine but i only have 18s on the back ,it is always the inner 15% that wears out first and they are due for renewal now ,have always fitted pirreli p zeros but i am gonno go for something a bit cheaper this time .have you the 10 inch rears on yours as it is normal for these to eat tyres

reads like run of the mill by the book geometry set-up, have you got a run of the mill car? "no" there is the problem... theroretical geometry scares most alignment centres back to the factory set-up, so time and time again the same wear appears if i were to calulate the geometry for the rear i would need the suspension height, the wheel off-set and a driver profile, then a theoretical but realistic camber and toe could be realized.

yep... approx 13 -15k for mine too.

I thought it was just my car.. but found it to be common amongst sports

I would guess Lexus GB just fitted the 18" wheels without considering the effects of the larger wheel and haven't issued specific geometry settings for the sport model. The factory settings were probably based on the standard 16" wheels.

[Tron20]

Late night again, could it be that lexus only issued geometry settings for the sport model with just the 18"x8" wheels all round, and just put the 10" wide rears on with the same geometry settings as a sport with 8" wide wheels?

Currently its my front inside edges that are wearing down, could someone tell me what this could be due to?

Thanks

Paul

[ColinBarber]

No Lexus wouldn't have even issued geometry setting for the 18"x8" wheels which is why they all wear on the inside edge. The 18"x10" just make it worse.

Take you car to someone like Tony who will be able to set the car up correctly. Clearly there is too much -ve camber.

[BEATTYM]

Thanks all for the reponses.

I have the optional 10" rear wheels which is making the wear situation worse as noted by Colin.

To Tron20, I originally had bad wear on the inner 15% of the front pair too but a local tyre fitting garage agreed to set up the geometry and camber (all the national chains wouldn't touch it!!). I then got 45K out of the next set of Conti-sports! Brilliant. However, the rear tyre wear problem persists.

The local tyre garage I use have suggested I get the rears set up by a specialist like Protyre in Bristol. Has any one else done this and were the results positive?

Cheers,

Marco.

[Steve]

protyre are ok.. but they just use the setting on the computer anyway.. tried this with protyre here.. they just used what was programmed.

[Tron20]

Tony have you had chance to setup the geometry settings on a lexus gs300 sport wither with or without the wider rear wheels? It would be nice to know the settings, surely driver profile being slightly different won't affect the settings that much, at least not as much as 18" alloys instead of the 16" standard settings

Edit :- Just to add the only wear I have seen on my tyres is the inside edge on the fronts, the rears as of yet haven't shown any uneven wear, just had to change the back two as they were on the wear marks

I have the 10" wide rears and I've recently changed all four tyres, but I don't know the mileage that the previous set had covered.

It had Pirelli P Zero Asimmetrico on the front and Michelin Pilot Sport on the rear. I've gone with Falken GRB FK-451 all round (as tyres go, they look quite smart too: http://www.falkentire.com/tires_451.htm ). I've used Falken tyres on previous cars without and problems and have been happy with their wear and performance.

Just found this site, currently debateing with Lexus in Exeter why I am on my 3rd set of front tyres in 30k miles on my gs300. Only the very inside edge wears, each time they say they have checked the alignment and that no problems exist.

they didnt tell me that its a regular problem which so many of these post seem to confirmed.

do you have any geometry printouts that you can display here.
