A common recurring question amongst new patrons to CelicaSupra.com is where to get replacements for the stock 225/60-14 tires. Assuming you're rocking the stock 14x7 P-Type rim (that seems to be the most common) you'll need to look around, availability keeps getting slimmer.

Quick Facts:

  • 82 - 86 P-Type is 14x7 +8 offset.
  • 82 - 84 L-Type is 14x5.5 +27mm offset.
  • 85 Only L-Type is 15x6 +20mm offset.
How to Read your Tire Size

Tires are rated with a series of numbers (most tires other than tractor, off-road/truck, and atv/bicycle tires) that read something like this 225/60-R14

The first number 225 is the actual width of the tread of the tire in Millimeters. This means the contact area of the tire is 225mm wide (or about 8.9")

The second number 60 is a RATIO, like a fraction. It is a ratio of how tall the tire sits off of the ground from the edge of the rim to the ground. This is called the Sidewall Profile In this case the 60 means that the height of the tire is 60% of the 225mm width. You can figure this out easily by multiplying 225*.6 (60%) which gives you a sidewall height of 135mm or about 5.3". The lower this number means the less rubber there is between the rim and the road. The benefit is increased handling performance because of less sidewall flex The downside is that you increase the chance damaging your rims from huge potholes, and the tires are much more difficult to install (yourself).

The last number R14 reads like this, the R simply means it's a Radial tire instead of a Bias tire. This is simply the modern standard method of manufacture, Bias-ply tires pretty much suck, don't ride or hold up as well for a number of reasons. If you want to know, go google it. Some tires will list the R others will not. The number we care about is the 14, this is the diameter of the tire/rim. You HAVE to match this number, otherwise the tire either won't fit, or you risk serious danger to your person and vehicle.

Use this Wheel/Tire Size Calculator for figuring out What Tire will fit what rim, and how much it will change your actual ground speed vs. indicated.

What tires Fit the Stock 14x7 Rim

Apparently the widest tire you can economically (by that I mean NOT cost $200 per tire) put on 7" wide 14" rim is a 245 tire in a 60 series.

A 215/60-14 tire would be ~1.1 mph slower

You have a ton of info that you did the research for. It is a great job and you made a little mistake. I commend you on taking the time to go through and do this since it will save a lot of people time when searching for tires for the stock rims.

I recently put a Michelin 215/60-14 up against a 225/60-14 cooper cobra, both on stock p wheels. Quick conclusions-215s give you straighter sidewall, thus utilizing more tread surface. Manufacturers specs vary, look closely at specs of same tire type in BOTH sizes mounted on 7 inch rim, and you will see that some 215s have similar or same tread width listed! Only drawback is if you need/want height(Speedo accuracy/Looks).

Yes great write up !! This tire calculator has helped me for years so maybe it can help someone here as well..:)

http://www.miata.net/garage/tirecalc.html

offset calculator

http://www.1010tires.com/WheelOffsetCalculator.asp
I never liked the Miata calculator because it doesn't properly update the image with the side by side comparison of overal tire height, sidewall height, and rim diameter.

Which is why I love this one over @ BigCustomWheels becuase you can play with both tire size, rim size, AND offset all at once and compare them.

I read this thread and because I did I was able to find some tires that I really needed. I had to go with a 235/60/R14. Got all 4 at Les Schwab for $450.00. And they are a T rated speed tire.
Later,

Glad I could help. It's great you found the tires you needed, however it's sad that production for these sizes is dropping and along with it the prices rising. Last year I got 4 235/60/R14's from Les Schwab in San Diego for about $400 or so installed.

I'm gonna render a guess, from my experience, that they are bf goodrich radial ta's or whatever.
That would be my guess - Tirerack.com has them for $81 plus shipping, if you have to pay to mount, Les Schwab is pretty much spot on...

The bf goodrich TA's are a T rated tire (112 mph). I don't plan to go over that often, but I do plan to go over it occasionally, hopefully in the quarter mile. I guess I will have to go to larger wheels, but to get the ones I want, I will have to go to 5 lugs. Wish I could find someone that just sells a 5 lug conversion.

Depending on the offset of the rims you want, there are 4 to 5 lug adapters. But I think if you do the front 5 lug swap and then take the hubs in to a machine shop to get them filled/drilled and new studs presses in, it will only be a little more expensive.

This site has 235/60/14's for really cheap, 4 shipped for $360

https://www.onlinetires.com


before i found this site i ordered two 235/60/14 from this place below for $181 shipped, looks like the place above is about the same or a hair cheeper depending on ur location.

http://stores.tirezoneusa.com/-strse-315/2356014/Detail.bok


either way i haven't been able to find any cooper 225/60/14's in about 2 years so finding the 235's is even better...i think one of the sites above even has 225's if someone is looking for them.

i've use the cooper's the yokohoma's avids and a kumo sub brand and one or 2 more and i personally think the cooper tires work the best with these cars.

A++
