Tire Size Recommendation for 18x9 & 18x10 - 2003-04 Mach 1 Registry Owners Club

brockmag · 09-04-2014, 11:43 AM

Just bought 18" FR500 wheels for my 03 and am not sure which size tires I should be looking for.

Fronts are 18x9 and rears are 18x10 - stock ride height, car is not lowered.

Thoughts?

brtnstrns · 09-04-2014, 11:55 AM

The tires that usually come with the kits are 275/35/18 and 285/35/18. But from what I've read you can toss a 305/35 (30?)/18 on the back and still be good which is what I plan to do for my next set of tires.

SuperMach1 · 09-05-2014, 07:15 AM

265/35 up front and 295/35 out back. A 305 out back would look nice.

Nice - I just had the same setup delivered the other day. I've been looking at tires as well.

Yeah.

I've been reading the same things.

Leaning towards a 265/35/18 front with 305/35/18 rears.

I'm starting to think this is the way to go ^

If you aren't racing I'd go with 265-35-18 or 275-35-18 in the front. 285-35-18 for the rear. It'd be ideal to keep the overall tire diameters the same or at least close. If you're wanting some bulge or a wider stance, then a 295-35-18 would be an ok choice.

I run a 265-35-18" Toyo Proxes T1 tire on the front 18-9" Saleen wheels.
I run a 305-35-18" Toyo Proxes R888 tire on the back 18-10" Saleen wheels.

Does it plow through corners with the different tires sizes?

NoSloCoupe · 09-15-2014, 01:30 PM

I was torn between 265 or 275 up front, in the end the 265 looked a bit too narrow for my taste in the many pics i looked at.

I went 275's up front and 295's out back...

Motor City Mach · 09-15-2014, 09:33 PM

I have 18x10 out back with a nitto 305 drag radial and it fits nice withonly a little bulge.

I jut ordered a set of true forged and will run a 335 30 18 on an 11 inch wheel pics to follow.

Mach32vZn · 10-08-2014, 06:38 PM

Hey did you ever get your wheels? Was hoping to see pics!

I have the tires but still waiting on the wheels. They take 6-10 weeks to arrive. I should have them in 2-3 weeks and then need to get them mounted. I hope it is a mild start to the winter and i should be able to take the cover off the car and get them on next month. I will post pics.

Jeff.Scherf · 11-08-2014, 05:10 PM

TTSleen and NoSloCoupe both look great!!

Question for you both: With those 18"s on their did you guys still go with any aftermarket springs? Both your cars look lower tan factory but that may just look that way with the larger wheels.

If so any clearance issues or recommendations on which you went with?

Thanks Jeff

NoSloCoupe · 11-09-2014, 11:01 AM

H&R SS springs(factory isolators) with Bilsteins, no issues at all....didn't even roll the lips.

I have coil overs front and rear.
UPR coil overs on the front (175# springs) and Raceland coil overs on the back.
Rear fender lips were rolled also to clear the new wheel/tires on the back.

iudelt89 · 11-11-2014, 12:30 PM

275/35/18 and 285/35/18 w/ H&R SS springs and isos. Tires fit well both front and back.
