Anyone Else Running 235/40/18's On Their Fox?

[FoxMustangLvr]

I have 18x9s with 235/40s all the way around. I posted some earlier pics on this that shows my rims protruding more than the Nitto's. Don't really like the way it looks. Maybe a different brand tire would be better or 8" wheels in the front.

I'd take a shot at some 245's on your front 18x9 wheels. 18x9 wheels with 245/40 tire don't really fit much different than 17x9 with 245/40 tire. I think 17"wheels are nice but once you get eighteens the seventeens just look a bit small. I'll probably never go down in size now that i've gone from 16" to 17" and now 18". IMO it's the perfect size wheel for our Fox.

275 on the fronts, 18x9. 285 on the rear, 18x10

275's up front? Are you running spacers?

 

[liljoe07]

275s... no spacers.

That would be my recommended tire size as well. How it fits all depends on the offset/BS of the wheels

Unless your AutoX'ing or doing road course racing there really is no need for that much tire up front. Kudos for fitting that up front but you're not able to get your car too low (if that's what you like) with that wide of a tire. Pretty much kicks coil overs to the curb as well which I just won't live without ever again on a Fox.

In that case, 245 is as narrow as I'd go on a 9" rim

I didn't do any fitting on purpose. I bought these rims with tires on them. I was actually thinking they were 245's until I looked last night. I think my fender well opening is about 25 1/2" from the ground. Not sure how much my car is lowered. It had cut Springs and no isolators when I bought it.

All 4?

yes, correct

Thanks! I was thinking the same thing. I found a pretty cool site that allows you to compare two different tire sizes and they will provide the exact differences in diameter, radius, width and sidewall. The 245/40/18 is basically the same diameter and width as the 245/45/17 which is a pretty popular tire size all the way around for the fox. I need to figure out how wide I can go on my rear 18x9 wheels without modifications. My 245s seem to have some more room- 255's should be no problem and possibly 265's?

Thanks. I'm on board with that. Not sure if a 245 will rub where my 235 doesn't at all

I searched previous posts for the widest rear tire I can fit on a 17x9 or 18x9 wheel without modifying the fenders. I don't mind getting a tire that requires the quads to be flipped, but just curious how wide I can go without doing anything at all.

I saw posts saying 255 was the widest which seemed small and others saying 275 is max without modifications.

My car has a 2" drop and I'm running 235/40/18. I have room to go a little wider. 245 seem pretty standard with tire/rims combos so I figure 255 is a safe bet and 265 is a maybe, but I could see the tires hitting the quads.

Experiences?

I run 275s on a 17x9 and they fit perfectly. Didn't have to roll the fenders or flip the quads. I don't have much room to spare though. My car is dropped about 1.25" the back, BTW.

I'm also going to measure my offset this weekend. Maybe part of this issue is the wheel sticks out pretty far from the car on the front. I've seen people run 265s and the tire is more tucked in than my 235s. Let me know what you think.

Wow that front wheel does poke out a bit far. To be technically correct, it's a real pain to measure offset on a wheel. What you will be measuring is backspacing, the distance from the mounting face of the hub to the inside edge of the wheel. Offset measures the hub mounting face to the center line of the wheel. I'm only saying this so we are on the same page when you return with a measurement From looking at that picture your backspace on that wheel is too low but probably typical of a 4 lug fox front wheel.

This is my Fox when I was 4 lug with 03' Cobra reps. They're a 17x9 with a 5.75" back space and fit OK in the wheel well.

X2 same on mine. I'm running nittos out back and they do run slightly narrower than some brands. 275's are fairly common on 17x9 setups.

275's here also. No rubs, no fender rolling, fit perfect. Car is lowered a good bit.

I'm with these chuckleheads.... 275/40/17 BFG comp 2's on 17 x9 Cobra

Thanks!

If I did my math right, my backspacing is 5.75" and my offset is 15.875mm. Would it be obvious if I had a spacer of some sort? I'll pull the wheel off this weekend and check closer.

275s all the way around? What is your offset and/or backspacing?
