Front tires ZHP, stock wheels. How wide can I go?

[vteckiller2000]

I haven't been able to bring up much in a search, I be a noob.

How wide can I go on the stock wheels and suspension of my ZHP coupe?

The PO installed 275-35-18's on the rear, and my ricer logic tells me to put 245-40-18 on the front for a uniform diameter, but I am not sure if it will work and play nice with all those pretty M suspension parts.

Help?

[danewilson77]

Mmmm....I think you may be able to get 245's on the front.....odds are 235's would be safe.

How do those 275's fit on the rear? Pretty snug? Pics please.

[vteckiller2000]

I am not sure, I just recently bought the car from a friend. He tried to replace the CCV system with his own homebrew hosery. It did not end well.

I have a good friend at a local BMW shop fixing it and replacing the entire CCV system, and anything else it needs. I have honestly never driven the car except onto and off of the trailer I used to pick it up.

I would love to just use stock sizing, but the rear 275's are brand new, and even a set of 255's are really expensive when there are a set of brand new rears on there... I'm kind of cheap to an extent.

[danewilson77]

So.....you have stock style 135's all the way around correct?

And you currently have 225's on front?

[vteckiller2000]

Correct, though the front tires are showing cords. Stock suspension, stock wheels, with proper widths and offsets, but with 275-35-18 on the rear.

[danewilson77]

ok.......so.......I think you should just go with 235's max in the front. Period. I'm not gonna make you calculate the clearance...etc...etc....

I need a pic of the ass of your car....asap.

[vteckiller2000]

I'll tell the tire shop to quote me the 235's, and I'll get a pic of the rear tomorrow, assuming it is not in the air on a hoist at the shop.

[danewilson77]

Takes pics in the air. I love pics.

Just recognize that 225's are stock for the zhp....on the front.

Stock setup = Wider Tires: 225/40ZR-18 in front and 255/35ZR-18 in the rear.

I know, the 225's on it just look so stretched on the wheels, and there appears to be a bit of extra clearance to the side of the strut.

I have right now 135's stock size with 255's all round.

[danewilson77]

^Like a Boss. Bi-winning!!!!

That's an expensive set of tires bro.

[vteckiller2000]

My old CSL reps were expensive too, 245/275 wide 19 inch. I am used to it.

If I can, I'd like to run 245's. If it is too close though, I'll do the 235's.

[HaloArchive]

Well, I use Toyo Proxes T1-R - 255/35/ZR18's - 280/AA/A - all round now that spring is here. They are good tires. Grippy. I think some places sell them for around $225 each. My fenders arnt rolled and, this is on stock suspension. No rub, even with full load of passengers and full trunk coming down or going up a steep driveway in Seattle.

[danewilson77]

Dayum...square with 255's...lol.

Das alotta meat.

Droid! Srs Legitness!

[mimalmo]

255 square isn't a problem though the front will look extra meaty since the wheel in front is only 8" wide.

Well, only downside with these tires is that they feel nice and soak up a lot of the harshness from the solid polyurethane FCABS and RTABS (that isnt a bad thing) but, it means the tires kind of fail as being pure performance tires. I do lots of driving long distance during the summer and don't want the car to be unbearably harsh on long drives as I wanted to keep the performance to comfort balance. But, for going around roundabouts at 50mph without tail slide, they work wonders.

[danewilson77]

Guy at tirerack told me the biggest tire I could put on an 8" rim was a 245...?

Droid! Srs Legitness!

[vteckiller2000]

Hmmm, I could use some cushion for the solid FCABS the PO installed...

[kaboom]

You can put a wider tire on an 8" wide rim, but your contact patch won't be much if any wider and you'll sacrifice a lot if turn in response.

Das phat yo.

And in need of a bath, yikes! 275's in the rear is crazy, that's way more meat than you need, unless you're supercharged/turbo'd, IMO.

[vteckiller2000]

The shop also has a set of 19" style 135 replicas with good tires. They said they would trade me for my authentic ones for free. I'm debating.

[az3579]

You can definitely fit 255's in the front. My auto-x setup is 255 square setup, with lower offset wheels. AND the car is lowered. No rubbing in the front.

Testing my first post here. Does the rear tire rub with the 275? I am thinking of getting the fattest tire I can in the rear without any rubbing issues.

Reason for going that wide in the rear? The zhp does not really need a tire that wide in the back.

Just for enhancing the staggered look.

Not worth it man to getting them to fit. You can try a 265 section width

[danewilson77]
