Tires/Wheels

sd88supra · 04-17-2012, 02:32 AM

Long ago, I remember there was a sticky for tires and wheels. After doing a search, I never found it.

I remember MrNickeleye had posted about different tires and wheels he had on his Supra. Very good info, unfortunately I don't remember everything. I was especially interested how they served him with his mountain driving.

I currently have 225/40/18 front and 265/40/18 in the rear; given that I constantly drive through bad roads, I was thinking about downsizing to 16" wheels to have bigger sidewall (3 flats was too many!). I already have four new 225/50/16 Yokohamas, only they've been in storage for 2.5 years, on a Supra that I put new tires on and stopped driving a month later. Can tires have issues when not in use for so long? They've been garaged all this time. I'm looking to just get new 16" wheels.

Anyway, for those of you with staggered setups on N/A's, have you noticed much difference turning sharp curves? I do mostly city driving so I don't mind compromising top speed for better acceleration, though I"m guessing it won't be much difference.

Anyone know how much the stock rims weigh? I've been trying to come up with a method for calculating the moment of inertia of different types of wheels; I'm guessing the stock ones are pretty heavy and have poor weight distribution. Has anybody gone for a staggered setup with the stock rims? How much more wider tires can go on stock size rims?

Thanks for your input.

It's in the MKIII FAQ section.

It's on the first page, title "Tire and Wheel Fitment Q&A"

You shouldn't have a problem with the tires if they aren't very old (5+ years or so) and were kept inflated while stored. Visually inspect the sidewalks for cracks, and check between the tread blocks for deep cracks indicating separation. Look at the DOT number on the sidewall (usually something like DOT XXXX XXX XXXX; most tires have a short number on one sidewall and the full number on the other) to find the tires date of manufacture. The last four numbers are the DOM, first 2 representing the week and last 2 the year. If the DOT number only has 3 numbers at the end, then it was manufactured before 2000 and likely not safe to drive on.
