I'm tire shopping online for one of my Formulas with stock 88 rims. I was looking at Tire Rack, but wasn't sure about the choices. They list only two types of stock tires for sale, the Falken Sincera SN250 A/S and the Riken Raptor HR. No treadware rating listed, and mixed reviews. What brand and model of tires are you folks using, and if you ordered online, what website did you use? Thanks.
I don't know whether Tirerack sells the specific size, but the General AltiMax RT45 is a good tire- and light, which makes our cars drive better. The tire in the 88 GT sizes does not show up when looking for them by size- but did show up as "Available" when I looked via "Brand" on Tirerack-et......Possibly, give them a call and talk to an actual Hu-man.....
Also, check with other suppliers, such as Discount Tire and Big O.....
I just talked to a guy at the TireRack, and he stated that the reason that General AltiMax RT45 tires do not show up on a Fiero Tire search is because the REAR size is not >>"H"<< rated...Now, I want to point out that while some of us Autocross and race Fieros, those people will usually have moved on to larger wheels and somewhat exotic tire sizes.
For those who are driving normal on regular roads, there really is no need for that "H" rating, so if you wish to buy these >>Very good<< tires in the correct size for your Fiero, try calling the TireRack, then dialing extension 4743 and talk to Cooper.
Tire sizes available in AltiMax RT45 tire; 205, 215, 225/60-15.
I'm looking into some tires that local shops and chains can get in a reasonable amount of time. I'm hoping to get tires mounted this week. What I have so far:
Hankook Kinergy PT H737 - around $120/tire
Goodyear Radial T/A (available black or raise white letters which might look good on an all black Formula) - around $200/tire
Anyone have experience with these?
Note: this car isn't intended for the track. It's a daily driver/beater type, but I don't want crap tires that will fall apart next year. I don't need track tires, but a upper medium quality would be good.

I don't know if the ratings have been modified since their inception, but I have found that the 15" tires with an 'H' rating had significantly stiffer sidewalls and enhanced handling and turn-in, as compared to the 'S' and 'T' rated tires.
Those Goodrich T/As are very heavy, very expensive, do not perform well.....back in the day they had a wear-rating around 300, so soft and sticky....Around 2000, they went to a wear-rating of 500- they will last for-ever...because they are hard as rocks and DO NOT stick at all.
Look into the General RT43 or 45....Good tire, lighter and much less expensive.

Damn. I ordered the T/As. These are going on the black Formula 3.4 which is an auto and kind of a beast compared to my 88GT. I run KYBs and there's some poly in the suspension so it's rough right out of the box and is expected. I'm sure it will work out. But I'll keep these recommendations for the Red Formula (to be built for handling) and the Yellow Formula, planned for a complete rebuild and 4.9 swap.

This seems to be accurate - I could only find 215/60-15 with a "T" rating. BUT-
The General AltiMax RT45 is available with an "H" rating in 225/60-15. I bought mine a couple of years ago, but Discount Tire still lists them. Not listed as a stock size for our cars, of course, but very close in diameter and just a bit wider.
Looks nice, use some dish soap and something to scrub the blue off the white letters, the bf Goodrich blue is thick and won't come off by itself, and after a few years of sun and wear look really bad, the white underneath is actual rubber in the tire, so don't be worried of scrubbing the white "off". I use Maguire's ultimate liquid wax on my tires, it is rubber safe, and keeps the tires clean (a simple hosing off cleans almost anything) and a nice deep black/clear white letters, not the dripping wet look from specific tire polishes, but it makes it look really nice.

I read about the blue thing, and asked the tire guy about it. I think he said "soap and water" but I'll give your idea a try, thanks.
