Default New tire thread?

Still learning how to navigate the forum and trying to use the search option to find a thread on new tires, but it only comes up when the word is used in a thread? Idk?
So I'll ask my question anyways,.. need tires on my 89, has Goodyear eagles F1's with excellent tread, minimal cracking in tread base, tires are 10 years old. Not buying these again for the same reason of aging out with good tread. Looking into Nitto, Toyos, Kuhmos, and others. Mostly just Cruising type driving with occasional high speed blasts.
​​​​Any recommendations to tires or thread to view?

An occaisional batch of 255 size tires are made, however, at this time I can not find 255's, I will be looking at 245 size tires, just for your information during your search.

Yes, All 17", unsure of exact width, I measured close to 10", so probably 9 3/4"

I had Nitto's on my 93, after a few days sitting they developed flat spots that took 10 minutes of driving to round out. I sold them and bought Continnel Extream Contact. They are much better but still develop flat spots but not as bad as the Nittos.

Here is what Mirrock corvette states about 1989 C4 wheel sizes. And below that is a Wheel offset explanation.

I am running Continental Extreme Contact Sport 275/40ZR17s on my 86 convertible. They were expensive but I’m very happy with them. They are smooth and quiet. Good warm weather traction and decent wet grip as well.

People! Let's stop guessing. The OP's car came from the factory with 17x9.5 "salad shooter" wheels like the ones for the base/Z51 89 in the picture Vets-Vet posted. If his wheels look like those, that's what he has. If not, then we need to know more info. The proper tire size is 275/40/17 like the OP has now, and there's no good reason to change that.

OP, do you drive the car in true winter conditions (below 20F or ice/snow)? If not, one option to consider are the Riken Raptor (under $500/set), which are high quality, decent performance (grip), and good looks. That's the budget tire of choice, no question. The best performance tire will be the Continental ExtremeContact Sport 02 ($947/set). It will have the best dry grip of any true street tire in this size except maybe the Michelin Pilot Sport PS2. However, unlike the PS2 it will also be the best tire in the rain - even better by far than any all-season. It's just not good for true winter conditions.

If you need a tire that can handle winter conditions, then you need a solid all-season. Let us know and I can recommend one or two of those, also.

I appreciate all the comments, yes matthewmiller I have the OE salad shooters. I will drive the car up until the county puts down the salt brine, which hasn't happening yet. I'll look into the brand tires you mentioned. Thanks, Mike

I'd like to add another endorsement for the Continental ExtremeContactSport. It's a phenomenal tire, and when summer comes around I'll be getting a set for my MX-5 as I have 0 complaints about their performance on my C4 in any aspect. In fact I was so impressed with them that I opted for a set of their VikingContact 7s on the MX-5 and they are also great.

For what its worth I just bought a pair of Mickey Thompson Super Street Comp's in the 315 size for my reproduction ZR1 Wheels. Have not read anything about them good or bad. I think they are a good looking Tire. They hold air and the car pushes around the shop better than the 17 year old Yokohama's that had been left for dead and flat with the weight of the car on them. I thought I would make a couple of test drives and burn them off. They were so hard they wouldn't leave rubber. Car drove like Freddy Flint Stones. I won't get a chance to test the Mickeys for about 2 1/2 months. $255 a tire in the 315 size. Funny thing is everything is going up in price but I paid $300 a tire in the 315 size 30 years ago.

the M/T Street Comp is pretty much the same tire as the Cooper RS3-S, which was a well regarded performance street and track tire about 10-12 years ago. As such, it's still a decent performance tire at a good price. It won't compete with the Conti in terms of grip or quality control, but it's not garbage like the Nitto 555. It's an easy recommendation in the 315/35/17 size because there are so few options and all the others except the Michelin PS AS 4 suck.

I assumed that they were made by Cooper. And I assumed they were made in the USA. But I didn't research that much as I didn't want to be disappointed. I have Kumho and Hoosier Track Tires. These are to get me to the Track.

The Continental brand looks like a good choice, especially when getting real world experience from members, (thanks for the comments members) Will be ordering off tire rack most likely then pulling all four wheels to get mounted. Been trying to find a local guy to mount and balance correctly and not have the "it's close enough attitude" when it comes to balancing. Its pretty much only box store type tire shops near me and I'm sick and tired of these "boys with beards" wanna-be mechanics or shop manager jerk-offs telling me what my vehicles need who work at these type establishments.

When you go to Tire Rack's site, you might try their search for installers they can ship to. That saves you the hassle of having to take new tires to a place, and at least they will have some clue about installing tires ordered from TR. They might even have a mobile installer who can come to you.

I just put 4 Michelin Pilot Sport All Season’s on my ‘93 over the summer. Went with tire re-size recommendation from this site since my car is staggered front/rear. Original sizes had limited avail and I wanted Michelins. Plenty of stock , tire rack has them and several of my local tire dealers had them next day. You could buy four of the 275/40R17’s and these are rated 98Y so it’s rated for 186 mph if that matters to you.

they are pricey to some but all I run on my vehicles are Michelins

I plan on getting 4 17x9.5 A-mold replica’s and getting two more 275/40R17’s for the front.

Tire rack quote attached….

The equivalent Michelin to the Continental ExtremeContact Sport that I recommended above is the Pilot Sport 4S. That's not an all-season, but like the Conti it is fantastic in the wet and will work well down to at least freezing temps. It's a true street "three-season" tire, or four-season tire if you live in the south. The PSAS4 that you got is only necessary if you drive in legit winter conditions: snow and ice or regularly in temps below maybe 25F. The equivalent Continental to that tire is the ExtremeContact DWS 06+. My point being, we are talking about two different categories of tires, and it didn't sound like the OP needs all-seasons.

Point taken.. I had never really given thought to driving all 4 seasons.
