Talking go with drag slicks!

Seriously man, the only way to get the "fat" tire look is to be running drag slicks... and they're not street-legal! I checked out Toyos line-up of street legal "drag" tires, and the largest size drag tire they will put on an 8" rim is 245! So, I'd listen to the guys that are saying 255s (or even 245s) max. Even though you may be able to squeeze it on... you will have cornering issues, possibility of tire slipping off the rim, blowouts, short tread-life, etc. Too many problems to be worth the "look", IMO.

Now you asked for recommendations (to create the "fat" look), so I would suggest you get a smaller rim (like 16x7) with a deep dish or concaved rim. The rim will need a smaller offset (even negative) to push the rim outwards and widen the wheel base. Then get the largest tire you can fit on it -- a 255/50ZR16 in this example will get you an overall width of 10"!!! (much wider than stock )

Haha, "wide" tires are very doable on a new edge. The pic of my car on the first page has 17x9 up front, and 17x10.5 out back. They are all Nitto extreme 555's fronts are 275, and rears are 315. These aren't wide compared to slicks though..... well BIG slicks, that is

275's?! Lmao. No. That pic is of my car, with 315's on the back mounted on 17x10.5" wheels. If you are even thinking of changing wheels, I'd do it now, so that you don't dump money down the drain on tires. READ: Different wheels will need different profile tires to look right.

Since you asked, *I* recommend you buy a new set of wheels if you want wider tires. If you don't have the money for new wheels and tires yet, get some cheap tires for now, and upgrade once you do. A full set of wheels and tires shouldn't cost you more than 1300, and that's with 315's in the back.

Yeah, I know "wide" tires are easily doable: I'm upgrading to 18x8.5" and 18x10s shortly myself... I thought the OP was looking to create a "fat" tire look like old school muscle (see pic) -- hence my recommendation.

I have 245s on my 18x8s so they fit perfect. 275s are wide so make sure u get the recommended rim width so they look good.

Look, you can squeeze that big of a tire on there, but it is a bad idea, especially if you like to corner. I have seen this exact setup "slip the bead" when cornering... And trust me, you don't want that, that's when the part of the tire engaged to the rim literally rolls out, the wheel comes crashing down onto the pavement, and if you not going slow when it happens, you will probably wreck the car. I'm not saying it can't be done, or that people haven't loved the results, but I have seen what happens when it goes bad, and it is not worth it, not even close. You will also lose some high speed stability and a lot of cornering capability, the tires will wear faster, and the gains in traction will not be in line with the gain in tire width. And it does't look the same as when it on a wider wheel. I'm not disparaging Thark, but if you look at his next to one with the same tires and wider wheels, there is a big difference. Do it at your own risk, but its not something I would ever do again, I learned the hard way, and it sucked a lot. Best wishes with whatever you choose, but manufacturers make recommendations based on a lot of research and testing by engineers, there are reasons why they say not to do it.

aright , I'm convinced with you all recommendations and I really appreciate that. I think I'm going with a 17x9 front / 17x10.5 rear as what i wanted in the first place but the money is a little short.

however, since we are talking about it. what yall think about 275/40/17 front , 315/35/17 rear set ? ( i know mrsinister said something about them, but who have them ) and would i need spacers all they way or just the rear tiers ?

I run 275/40/17 Rear and 255/45/17 front on my 17X8 Cobra rims, never had an issue, 275 is the Max for an 8 inch rim though!
Lots of guys posting are doom and gloom with this tire size for the rear? EVERYBODY I know runs them. Yeah it might be an issue on a road course taking corners at 90 mph, but for daily driving at respectable speeds their fine!
The rear wheel wells are so big and deep putting 245's on the back looks like crap especially if the car hasn't been lowered!

You can run a 275 on an 8, its about the biggest tire you can get on there and it will compromise some performance but it can be done. As for brand, i would go with nitto's. I have nitto 255's all the way around my car and i love them. It would be a good idea to either get new rims or smaller tires, but if you really want to you can do it run 275's.

Thanks silver, but I'd prefer to think people choose to listen because of what I have to say rather than the name. To be honest, like pretty much everyone on here, it doesn't really matter if anyone listens, we're all here to enjoy our cars and help each other out. As far as the front tire width, it depends on what you plan on using the car for, wider fronts will make it slower on the drag strip, but it will handle turns better if they're on the right size wheels. In the back, 315's offer much better grip on a 10.5" wheel. Also, the wider the "footprint" the more the rolling resistance, it can lower mileage and acceleration if you overdo it, especially up front. And by the way mrsinister, your car looks sick from behind, I love it.

I have 275/40/zr17 up front and 315/35/zr17 out back. This keeps sidewall height the same on the tires, and still gives a super aggressive stance.

You won't need spacers for those. Just as long as they are wheels for 99-04 mustang. Here's a couple pics of my car with 17x9 and 17x10.5's

well since i just read every word of this post i would like to throw my experience in here. a friend and i both have the same exact 275 nittos on the back, but i have a 17x9 and he has the 17x8. he hooks okay at the strip, but he says in daily driving he feels uncomfortable with the tires because like everyone keeps on saying its way too much tire for the rim. and it does wear funny, you just have to play with the tire pressures to get the tire to sit right, that was another complaint he had about it. however with me, i hook great at the track and feel confident going into corners hard. the tires actually suprised me with how stable they are launching, high speeds, and cornering. i'm hooked i guess

00 Kenne Bell GT vert: Sold
04 Sonic Blue GT: Missed
