I've been reading up on 2013 Boss spare tires, including orange3.9stang's post #24 above; summarizing, search for 2007-09 GT500 18" wheels at D-T-D -- the Drag 18x8 DR-34 is mentioned -- then mount a 225/50/18 Goodyear Eagle LS2 tire. It will stick up about 1.5".

I have a 2013 Laguna Seca, which has different wheels from the non-LS. The silver Drag DR-50 looks pretty similar to an LS wheel. D-T-D shows the 18x7 DR-50 (5x114.3, 40mm offset) as fitting a 2009 GT500.

Tirerack shows the 225/50/18 LS2 with a rim width range of 6-8", with a measuring rim width of 7".

So my 2013 Boss LS spare tire plan: 225/50/18 Goodyear Eagle LS2 mounted on a 18x7 Drag DR-50 wheel.

Any holes in my logic?

Good can of fix-a-flat and a tire plug kit, it works great in conjunction with those TPMS sensors since they let you know when the tire is failing.

I picked up a nail in one of the old rear tires and ejected the nail, the TPMS light went off and I managed to get the car off the highway. The factory fix-a-flat could not slow the puncture or plug it up, but the plug kit managed that just fine and off I went after pumping up the tire. The whole procedure took substantially less time than the wait for a tow truck and in a situation like yours won't leave you stranded if your outside the tow truck service area.

For those people who insist on disabling the TPMS system, keep AAA handy as the same scenario substantially increases the chance of catastrophic tire failure as more than likely at highway speeds the deflating tire wont provide as much warning before it fails rendering the air pump, fix-a-flat, and plug kit completely useless.

Those Tmps sensors have saved me a few hundred dollars. ..... Along with time sitting on side of road ....

I did end up buying an 18x7 Drag DR-50 wheel with a 225/50/18 Nankang AS-1. Nice that it gets mounted and balanced by discounttiredirect.com; it shipped unboxed, with the shipping label taped to the inside of the rim.

Fully inflated, it fits quite snugly into the wheel well. As noted in this thread, the trunk floor panel does stick up 1 3/8". I was debating purchasing a used 205/55/18 Pirelli -- search on ebay -- but decided to purchase a new tire, with the complimentary mount and balance.

I hope I never need the spare!

I am interested in a spare as well. I just wished ford made a spare for the brembo people. Why didn't u buy 205 tires? Is the diameter not the same as the oem tires?

Does the dr50 fit rear & fronts as well?

Sorry to resurrect this topic, but I was helping a GT500 buddy on this very topic today, and sent him a link to this thread. I just noticed the follow-up questions.... Better late than never.

A 205/55/18 tire would also have worked. It's the same 26.9" diameter; presumably the width would have been 20mm less (than a 225/50/18 tire). So the trunk carpeting/pad would be lifted 20mm less. But 205/55/18 is a weird size; tirerack shows no tires in that size. There was one used Pirelli in that size on ebay, but the price was not reasonable to me.

Turns out, my left rear tire picked up two screws about six months ago, and I did use this spare tire. Unsurprisingly, it cleared the rear brakes. I have not personally tested clearing the front brakes, but I have read on the interwebs that this wheel clears the fronts. (And as others have mentioned, worst-case with a flat front: put a rear wheel on the front, and put the spare on the rear.)
