Differences in wheel width

Toyota won't sell you the 18" TRD wheel and tire package in the USA in a non-staggered configuration. This configuration certainly does not "mess with the traction control systems" though I can imagine a more extreme setup may be a problem.

Reworded for your enjoyment.

It's a package, of course they won't sell a package broken up, it wouldn't be called a "package". You can still order the wheels individually though.

What messes up the traction control systems is not the tire width, it's the overall diameter. If the front tire takes 77 inches to roll out and the rear tire takes 85 inches to roll out, now your tires are rotating at two different speeds and the traction control freaks out. So if you want to run staggered, you try to keep the overall diameters very similar. Usually this means jumping three tread width sizes. 215/40-18 (24.77 OD) on the front, 245/35-18 (24.75 OD) on the rear. That kind of thing. 225f/255r is very common; 235f/265r is somewhat common. Or you keep the sizes square and not worry about it.

I have some questions about a similar situation, I'm getting 18x8s. Cant decide if i should go 225/40s or 245/35s tires. Pros/Cons with each?
Im guessing 245s:
+rim protection
+grip
-handling
-steering responsiveness
-ride quality

Is this correct? What about just the 245s in the rear?

What is the offset?

On an 8" wheel, I'd do 225's all around. A 245 would probably fit, but it'd be pinched. If you were doing 8.5" or 9" width, I'd do a 245. There's zero reason to run staggered tires on square wheels. If you want the back to come out a little to be flush with the fender, spacers work just fine.

The steering wheel will be a little heavier with 245's because it has more traction. Gas mileage will be a little worse, because you're moving a heavier tire. Ride quality depends on the tire itself, not the size. Going from the OEM Primacies to Pilot Super Sports in OEM size, ride quality suffered a lot because the sidewall is so much stiffer.

Why do you want wider tires? If you're putting down a lot of power or you're taking it to the track or you need more traction or if you just want huge fat tires to look cool, great. Just make sure you know what the tradeoffs are before you make your decision.

@gramicci101

Thanks for all the info. It's helped me out enough.

I've made my final choice of going 245/35/18 on 18 x 8.5

Going with TSW nurburgrings with 18x8 +35mm for looks, weight, costs mostly.. with the potential chance of a BBK and coilovers down the road.

TireRack has fewer than 3 and it takes 7-10 business days fr Enkei to send them more. Sad Panda

That will look perfect with 225's and won't have any problem clearing a spring and strut suspension.

That's disappointing. Have you tried forum sponsors? They might have it in stock or be able to get it faster.

Also, when you do get them, post a pic thread so it can be added to the wheel database. There are no TS9's listed right now.


Edit: Here's an 18x8.5 +42 with a 245 tire. The TS9 is a +40, so they would be pushed 2mm further out than these are. He also went with 245/40 instead of 245/35, so his tire is about an inch taller than OEM.

No Worries, they just got back in stock. I pulled the trigger. Should be here this week or next.

Pictures definitely coming!
