275 or 285

[jbailer]

Whichever one you can get the tire for the cheapest... you won't notice all that much handling improvement from the 285 on a 10" wheel.

Really? Why is that? I just always think more is better as long as it isn't too wide for the wheel.

I typically run a 275 up front and it's grippy even with cheap nearly done Coopers. 285 will have more grip sure but noticeable on the street? Meh... doubt it. If you got the money, go for it.

I just went through this decision as well.
Ordered the SVE GT350 20x10 wheels and found 285\35\20 BFG Gforce Comp 2's are fairly inexpensive ($729 shipped set at tirerack.) Did some calling around and got them for $720 out the door - mounted and balanced @ discount tire.

Tirerack has 275/35ZR-20 CONTINENTAL EXTREMECONTACT DW XL on close out for $132.66 each. I just purchased 4.

Not all tires are remotely equal when talking about tread width. Some manufacturers vary greatly even in the same size tire (MPSS 275/35, 3 models from 9.5 - 10.3"). Heck, BFG Comp2 275/40/19 has a wider tread than their 285/35/19...

Check each tire's specs if it means that much to you.

What size can the 19" PP size max out at? P-Zero are starting to become an issue.

For which replacement tire? Fittings vary by tire model.

Looks like I might roll with the MPSS, I think my rims are 9.0 front and 9.5 backs correct? So probably 275 front (might be overkill) and 285 rear...

Looks like this thread got a little sidetracked

You own an EB model not sure why running 285's on the street is really necessary?

But hey! They look awesome. I've seen a square 285x19 setup on a GT and it looks great. Can't remember the rims it had.

I am now saving up for my next "big" purchase which will be a set of wheels and tires. After a lot of thought and research, I've settled on a square set up consisting of the 20x10 SVE GT 350 replicas. They are much more budget friendly than a lot of the other options out there, and I like the fact that I can run a square set up without worrying about spacers, etc. For tires I have decided on the Firehawk Indy 500 based on the reviews I've read here and elsewhere on the intarweb. Originally, the plan was to go with 275/35/20 all the way around. But, in comparing the prices, I realized I can get 285/35/20 for about $12 more per tire. So, I have a few options which I would love to get everyone's opinions on. The options I am considering are:
- Run 275's all around
- Run 285's all around (will they fit)
- Run 275's up front and 285's out back.
A little about my car - it's lowered on Steeda progressive springs. It is my daily driver and I don't ever track it, or have any plans to do so. I'm more about straight line performance, but do like a twisty road every now and then. I do like the idea of being able to rotate my tires, but it is not a deal breaker. I do worry a little bit that if I do run staggered tires that I may not be able to get the same tires when it's time to replace there rears (I've read that you typically replace the rear tires in about half the time of the fronts and I don't want to have mismatched tires). I also like the look of a meatier tire (that I'm assuming the 285 would give me) and the idea of having a little extra protection around the wheel is nice, especially on a daily driver. I'd appreciate any advice you all have to share.

BTW, Tirerack has this deal going, which seems like a good deal. If they're still available when I have the cash, I may go this route.

I had no idea there was that much variation within tires of the same size. I figured 275 mm is 275 mm no matter who makes the tires. Either way, we're talking a few mm here and there. I'm sure I won't notice a difference on the street. It's really going to come down to what deals are available when I'm ready to buy.

I saw those. That is the deal that I linked in my original post. I really hope they are still available when I am ready to buy. It looks they're phasing them out in favor of a newer version. Discount Tire also carries them, which means I'll be able to avoid shipping costs.

Go 275/40 and 255/40 or if you can swallow the price, throw on the 285/40 on the back. I ran that setup for a while, including track days, and was quite happy with it.

Sounds like a GT owner with no clue... You think because it's an Ecoboost it will be going any slower around corners or it can't use the traction coming out of corners? :doh:

Umm... yeah, thanks for getting the thread "back on track" with your "contribution". Nobody said anything about being "necessary". If we all only did what was "necessary" we'd all be driving around in stock cars. The question is what the benefits of a slightly wider tire on my car (a lowly EB )would be and whether those benefits are worth the price difference.

Wider tire offers basically better traction, along with better braking also. Hell even helps out with less hydroplaning, if we get that extreme in driving. Plus it just looks great but too big on a rim could piss off the sidewalls. addle:

Exactly, and like everything else, it's all about finding a balance between performance, practicality, and budget. I'm confident now that I'll be fine with whichever of the 3 options I choose. Thank you all for your help.
