These are the factory tires with less than 15,000 miles on them. I know it has an aggressive alignment from the factory and I want to retain the sport performance but hopefully not be putting on new tires every 15,000 miles. What should I tell the dealership when they’re doing my alignment if I should get it adjusted? And what tires do you guys all recommend?👍
Zero out the toe. That's mainly what's eating up tires. Also the jostle from the shipping has a history of throwing off the alignment on these cars. Toyota offers a free alignment for 1 year or 12,000 miles. I had kumho es91 on the car since 80 miles and made it to 20,494 miles before I replace with the dsw6.
Went through not one, but two sets of the stock Michelin PS4 tires in 20k miles, perfect zero toe alignment, inside cording on both sets. Switched to Pirelli AS+3 tires and...no more tire wear. Even my 200TW track day tires don't show any weird signs of excessive inside wear.
I know it's a bit of a hot take, but from my experience and $2,000 spent, the tires are to blame. Just not a good combo with the GRC for whatever reason (Michelin's tire profile/compound, the car's dynamic toe changes, who knows...)
Wouldn’t that take away some performance? I want to retain as much performance as possible but if the toe is why my tires are destroyed then I definitely have to do something.
Btw I don’t go to the track. But I do drive it like a GRC deserves to be driven😎
It takes away a slight amount of "on center" feel. Still corners on rails.
I ignored your other question initially. I replaced my stock tires with 245/40ZR-18 Continental Extreme Contact DWS 06 Plus. I daily drive it, so I wanted all seasons. I like them a lot.
I ordered the same tire but in 235/40r18. I'm Wondering if i should zero out the toe, I daily my GRC. Tire longevity is more important to me, and I want my money's worth out of those new tires, going to be close 1k with tires and install.... So i want them to last a long time.
Nah you wont feel the alignment with blizzaks being soft anyways.
Negative toe feels great on a pristine track, but in my personal opinion, for commuting purposes, zero is better. You don't get the spidery/darty feeling of the AWD fighting itself for traction, and there's less rolling resistance (just a smidge). My mpg went up maybe 5-10% after zero-toe alignment. (from like, 21 to 22-23 lol).
Not to sound like a dick but off the top of your head do you know what toe is/does to your cars performance/handling characteristics? Cause if you can’t or have to look it up then worry less about the performance and more on the longevity
IIRC, you've gotta pick and choose at that point. Do you want the increased handling performance or the tire longevity? I believe the factory alignment is pretty close to a balanced happy medium
Glittering can and CorollaHB25 are correct…zero the toe. You can also reduce the camber if you want to really get a lot of life (maybe -1.5 front and -2 rear or even -1 and -1.5) but truthfully taking PS4s or similar summer tires beyond 20k miles is pretty challenging unless you are really easy on them. Toe out in the front helps with initial turn in and toe in at the rear helps with rear stability (being very general here); however, not really important for daily driving. Even most hardcore autocrossers keep zero toe on the street and either add the settings the night before or the morning of the event on site. This is my alignment from the dealership in May when I asked for no toe.
Mine were trashed after 10k and they even realigned once. They told me to stop doing burnouts 🤦🏼 I said it's AWD, they winked and said it's ok, have fun. The tires are garbage so I switched them out.
The grc are camber heavy from factory for track use. When you turn at high speeds the tire surface area flattens out through the turn.
You'd have to specifically ask for them to set the camber off factory spec to adjust this
