Which width wheels and tires?

[laspariahs]

I'm looking at putting 19x10 with a 40 offset all the way around on my 2011 mustang GT brembo, is this a good set of wheels, will they fit properly? They are the TSW Nurburgring wheels.

Thoughts, suggestions?

This one will fit. they don't have 10" listed on their site. only 9.5 and 10.5 and none of the 10.5's listed have the correct offset for the bolt pattern. they may be made but tires direct usually carries all the sizes...

most 285 tires have a minimum wheel width of 9.5 or 10. you can probably run up to a 305 on them with no problem but the wheel is going to float around in the sidewalls a lot more

What's the fattest tire I can get on there reasonably. And what about the height? stock they are 255/40/19s, do I need to stay ---/40/19, or could I go to a 35?

Sorry I'm kind of new to this....

 

[JesseW.]

you're probably going to have to go xxx/35 as the side wall height is a function of width. so the wider tire, the higher the side wall. the 255/40-19 is 27.1 inches in diameter. a 285/35-19 is 26.9- so very close. the minimum recommend width for 285 is 9.5 for most 19 inch wheels. 295 is 10. 305 is 10.5. i believe 295 is the widest tire you can put in the front of the car without changing balljoints and a caster camber plate. i'm running 285/35-18's all the way around on my car right now with a 9.5wide +35offset 18inch wheel.

if you can get the correct offset and width wheels a 315 will fit in the back. but you aren't going to do it with those wheels.

Sounds good, thanks for all the info. I'm wanting to keep the tires front and back the same, so I can rotate, unless there's a huge benefit of going with a much wider rear tire? I get the more traction for the drive wheels part, but it seems like it would handle funky and just be a pain in the ass in general.

So it sounds like 285/35/19s, on the 19x9.5 rims.

Thanks again for the help.

Ya I wish they made them in a 19x10. But like stated, your stuck with a 9.5.

 

[wesleyk5]

YES. TSW Nurburgring 19x9.5 will clear Brembos on the '11 gt. I believe the 19's weigh in at ABOUT 19#s(my 20's weighed in at 21#s). They are forged so they are very strong too.

They make 20" that fit perfect. The 20"x9.5 only weighs 24lbs that is less than the stock wheel. I have had 275x35 on the front no problem. Check the Tiger racing hood thread Paul mentions running 10" and even 10.5" on the front.

 

[laspariahs]

OK, I'm thinking of pulling the trigger on the 20x10 with a 114.3 bolt pattern, and offset of 40, good to go?

The tires are a 295/30/20. All the way round.

Sound good? Handle well, drive perfectly?


I'm excited!!

I don't mean to thread jack but I'm falling in love with the TSW Nurburgring too! Only thing is the offset.... 40mm. I've noticed the 20 x 10 in the rear sticks our a bit (not flush with the fender). Any idea what would be the ideal offset?

My co. is direct with TSW and they do not make the 10.5 in the right fitment for the s197 platform.

I am sorry but they do make a 10.5"x20" with 63 mm of offset which fits the back of a 2010 Mustang perfect. I know I tried it. I did decide to add a 1/4" spacer but it is not needed.

he was discussing the 19" wheels in the beginning...

and he wants the same size all the way around to rotate. a 10.5 with a 63 offset on the front would be REALLY close to hitting the struts without spacers.

Hey guys, so will the wheel and tire package of 20x10 40mm offset and 295/30/20 tires work or????? Just want to be sure before I fork over the money.

it will probably work, but that's going to be aggressive and might hit the rear fenders. it's roughly the same as my 9.5 +35 offset on how flush it is, but i'm running a 285/35-18 so it's a lot shorter and a little narrower than a 295/30-20. I would have an adj. panhard bar ready for when you put those on if your car is lowered... or go with a 275 tire and stretch it.

my tire sticks out from the fenders everywhere but the very top, where it just does clear the inside edge. i don't know if a 295/30-20 would with that width and offset.

to give you an idea, this is what mine looks like, and a 295/30-20 is going to be wider and taller.

Cool, my car isn't lowered so it sound like it should work well, if I need to I can just go down to a smaller tire, or should I just go with a 285 tire to start with?

You car looks awesome!

 

[JesseW.]

the extra 10mm isn't going to do that much for grip. if you're car isn't supercharged it's going to have a hard time spinning 285's in a 20 inch wheel. the compound of the tire is a lot more important to grip than the width. are you planning on autocrossing or doing trackdays with it?
if so, i'd go with 18's for the performance advantage and tire choice/prices. if not, 20's really do look sweet on the s197's

the blue car in this thread has TSW 20x10's with a 285 on the back and is lowered, not sure of the offset but its probably the same as the nurburgrings, so i'm thinking it'll fit

Yeah, honestly I'm really really torn between going 20x10 TSW nurburgrings or 18x9.5 Enkei PF01s..... Since I know the Enkeis will go over the brembo brakes in a 18.

While I don't think I'll track the car much, I do want to, and I like the idea of the lighter wheel that the Enkei provides, also the tire choices/cost of tires. However I love love love the way the 20x10 TSW's look. I know the width won't do much for traction, as mentioned above I'd love 20x9.5s or even 20x9s.

I know I'm all over the place, but I want to do this only once, and do it right. Thanks for all the help.

 

[JesseW.]

i'm pretty confident even the 18" tsw will clear the brembo's. the inner rim diameter usually isn't the problem with 18" wheels and brembo's, its the spoke placement. a wheel with a lot of lip and flat spokes on the back is going to have a lot more issues. the tsw's spokes are flush with the outside and achieve offset with leaving material on the hub, so it's got plenty of room behind the spokes. the 18" tsw's and 18" PF01's are pretty close in weight too.

 

[wesleyk5]

Even the Nurburgring in a 20x8.5 clears the Brembos with plenty of room. The 20x10's have even more clearance for the big brakes. The 20x10's will clear your brakes. Always test fit wheels before mounting tires though. I sell and install HRE, Fikse, Kinesis, TSW, MHT(Foose), among many others for a living. This is always a rule. What JesseW. said is true. It is the back cut of the wheel the matters the most when it comes to 18" and up size wheels to clear big brakes. And traction(compound) does usaully matter more than tire width.
