I want a wider tire on 07 Exige S. I want Yoko A048’s 225/50 - 16 up front and 245/40 - 17 rear. Is anyone running this setup..? If so, are there any rubbing issues..? I need to get a set soon and want to get a wider setup… Any input/advice would greatly be appreciated…

i've got 235/40/17 in the back and its fine. I've got both arch liners off right now and there was zero rubbing. You didnt mention the wheels....aftermarket? Cause I dont know if the stock rears can even safely hold a 245 series.

245's are fine, but I'm not sure about the yoko A048 245, as the tread width is 9.8" wide, in other words...huge. Stock 225's are 8.8" TW, and the popular S-Drive Summer tires are the same 8.8" TW.

Tire rack is your friend. Also, do a quick search on R888.

I have the stock LSS Exige S wheels. I want to go wider on the tires and I'm checking to see if the 225 on the front and 245 on the rear will fit without rubbing

225/50 seems a strange choice, very tall.

If you're looking to preserve the same ratio as stock:

205/45R16 + 235/40R17 (about 1/2 inch shorter)
215/45R16 + 245/40R17 (marginally shorter)

If you do want a 225 up front, go with a 225/45r16 which will only be .3" taller, as opposed to the 225/50r16 which is 1.2" taller, and will likely rub. If you have tires that can handle 225/45r16 up front, get a 255/40r17 rear to match it.

What some people are doing is going to a smaller rim size and getting:
225/45/15 front and 245/45/16 which seems closer to what you wanted.

and the popular S-Drive Summer tires
I don't think the S.Drive are all that popular! A fine rain tire, but you sacrifice much performance. (See http://www.lotustalk.com/forums/f91/another-need-help-deciding-tire-should-i-get-thread-poll-71228/ post #14)

Your rims are 6.5" wide in front and 7.5" wide in rear. Depending on your tire you get you might also have issues finding a 225f/245r that will fit on the rims.

Check out this chart: http://www.rallysport.ca/wheels_tires/product_photos/AO48.pdf to see which tires will actually fit on the rims you have.

Looks like 205 up front and 235 rear is widest for those rims and AO48s. You could consider a different tire.

It should also be pointed out that the AO48 LTS (increased performance AO48s for Lotus) are only available in stock sizes, by changing widths you'll be dropping down a step in UTQG rating, another reason to consider another tire brand, for example the Toyo R888.

They have Hankook RS2's in 205-45 16 and 235-40-17. They praise them on the miata.net forum (then again they praise EBC brake pads). I figured I'd give them a try on my miata and WOW they're great on the street all around (heavy rain since its my DD). I'm taking both the exige and the miata to the track this weekend (my dads driving the miata but we will switch) so I will see how they are on the track. They're great tires and affordable, anyone tried them on an elise/exige?

I think I might order a set since I'll be at the track fo three days this weekend possibly followed by a dragon run on 1-2 (summer vacation time). They're $96 for a front and $122 for the rears. 200 AA A in the front but 200 A A in the rear.

I have 205/45 and 245/40 on my stock lss rims (reo1rs which run a bit wide as well with no problems. I think a 225 up fron will be too wide for stock fronts (6 or 6.5"?). I am not sure about rubbing up front but I fear that combo would give a bit too much front bias and make for a twitch rear end at the limit....

You will need wider wheels up front for sure. The side wall flex on that size tire on the stock wheel will kill your handling.

to me a 225 is over kill

I have 245 AO48s on 8" wheels. No rubbing. I have all my camber shims on the car as well and it's lowered as far as track pack will allow.

**** is running 255 R888s on 8" wheels with no rubbing (IIRC) but he has all camber shims removed. I might try the 255 R888s next. I think the sidewalls on those are more straight than on the ao48s. ???

Will the 215/45/16 fit without rubbing in the front? It would be nice to get the new Kumho XS in that size.

I have not been able to find a 205/45/16 AO48 for the front at TireRack. For the rear they have the 235/45/17, but do not have a 245/45/17… So what other options are there for the LSS rims with the performance of the AO48’s for the front/rear..?

I need to get a set of tires ASAP….

It looks like I will go with the Toyo R888 205/45-16 front and 245/40-17 rear on my stock lss rims. Is this a good combination and if so, where is a good place to order them from..?

Good price on the Toyo R888 here: Performance Tires Online|Treadzone.com Tire Specialists

I went with the 205/55/16 front and 235/45/17 rear on TR Motorsports F1 rims which gives a 24.9" front diameter and a 25.3" rear diameter - provides a little downforce "rake" - these are the widest tires that should fit my TR rims and keep from too much oversteer. They did not have a 205/45/16 available.

Use this calculator to compare different front/rear sizes: Tire size calculator

Edit: The tires shipped in today - looks like the 205/55/16 is going to be too tall to risk a fender rub... I am going to try to trade em for the 195s but will
keep the 235s in rear - also plan to pull some shims and learn how to check camber.

i just mounted 235/45/17 (hankook RS2 Z212) reartires on my rims today.
I took it out on the parkinglot for some hard cornering, and i could see some rubbing on the plastic front of the left tire furthest in.

I wanted the 235/40/17 but he had the the 45s in stock and the tireguy said it shuldnt be a problem. i kinda regret already, as i feel that the acceleration is much slower than it was before. i could just be my imagination tho.

on normal driving the hankooks feel pretty ok to drive with tho.

edit: im used to A048 225/45/17
