I recently purchased a 1990. It needs new tires as the current ones are dry rotted, according to the specs it should have P275/40ZR-17 B/W High-speed steel-belted radial Eagle ZR40 unidirectional (Goodyear) on them. I was speaking with a gentleman about tires and he recommended I go wider in the back then in the front. Is this a good option and if so, what sizes should I get? Or should I stick to the manufacturers spec. It will only be driven during the summer and only for cruising no racing.
People go with bigger tires in the rear for looks or for increased traction. I would stay with the 275's if you're just cruising. You can't go with a much wider tire anyway without wider wheels. It's common for people to replace stock wheels with reproduction ZR-1 style five spoke wheels, and a lot of people will go with 9.5" wheels in the front with stock size tires, and 11" wheels in the rear with 315 tires. So if you like that look and want to buy wheels as well as tires go for it, otherwise the stock 275's work just fine.
I've got Goodyear Eagle Asymmetric AS 275s on my '90 all the way around. Same thing, just a cruiser.
I've only driven the car at triple digit speeds a few times, mostly just drive the winding back roads. They stick just fine for me. And they're quiet. They handle well. I'm content with em, they work well for what I use em for.
(Achilles ATR 275/35R18 99W) as my car is mostly for cruising but I'm actually totally loving them. They look badass and perform incredibly. The only thing I wish I'd done differently is get the 40 height instead of the 35. The 35's have a flatter/thinner sidewall. But at $64 a tire shipped I figured if I hated them I'd upgrade to some high dollar tires this summer. I'm loving them though so I'll keep them.
You mentioned whether to go bigger tires/wheels in the back and the other question most guys with vettes this year have is whether to go with a larger diameter wheel in the back. I chose to go with the same diameter (18") and width front and back and they look amazing and the stance is perfect. My stock wheels where 17" diameter front and back and the same width for what it's worth.
I also chose to replace the rotors with drill/slots and new pads and some caliper covers (I'm in the rust belt so even painting calipers is a losing battle with rust so the caliper covers are aluminum powdercoated),

Thanks in advance for any advice and help.
Stick with your OEM wheels, they are a 1 year only wheel. The 275's are just fine, we're not talking about a butt load of HP here.
Thanks everyone for the comments and advice. I have been doing some research on the side and it does look like for my particular application sticking with the stock tires will be the better way to go. Being a new to corvette ownership I am looking for as much advice as possible and I appreciate the more experienced owners feedback.
Was talking to someone the other day. If the car came with 275 40R17 all around, could you use 275 40R17 for the front and 315 35R17 for the rear since that is a ZR1? That is, unless the rear wheels are different?

I'm not sure what your question is. 1990 L98 cars all came with 9.5" wheels with 275 tires all around. ZR-1's came with 9.5" wheels with 275 tires on the front and 11" wheels with 315 tires at the rear. If you want to run 315 tires on the rear you need 11' wheels (at least they should be wider than 9.5"). That's generally what people do when they put wider rear tires on L98 and LT1 cars, although the offset is different than the ZR-1 wheels.

If the wheels are different I guess running 315 tires is out of the question.

OEM 11" wheels will fit, but will be out past the edge of the fender. There are after market wheels with the correct offset that will work. I think what most people don't realize is that the ZR1 rear body panels and facia are 3" wider than the base model convertible and coupe to fit the wider tires.

I was wondering about the rear tires as to whether they would fit on the rim but I didn't have the spec so wasn't sure.
I'm new to the forum and not sure if this is the best place to post this(any suggestions on where a question like this is best placed is much appreciated). I have a 1990 Corvette that I've done minor work to(replaced blower injector and instrument cluster) but I'm really looking to improve the sound. I believe it currently has the stock exhaust but I'm not positive. Basically I want to update the cam, headers, exhaust, cold air intake and anything along the way you all feel could provide improvement I guess what I'm wondering is what order should I do these things in? I don't want to put the cart before the horse and do something that could be needless/repetitive. Thank you for any insight.
1990 Corvette options
Grandsport (50mm) offset vs. ZR-1 (36mm) offset. 11" wheels with 50mm offset work for non-ZR-1 cars.
