Tires on ZHP
 
I just purchased the 10 spoke 18" rims that come on the ZHP. I have 17" now (in great shape w/brand new tires on them). I don't want a really low profile (i have 205/50/17 now) and wanted to keep the same height on the new tires. Does anyone know what tires come on these rims from the factory?

Thanks

I found it - just in case anyone else wanted the info...
The tires are 255/35/18.

^ That's the size of the rear tires.

Fronts are 225/40/18

zhp wheels are a huge downgrade in terms of performance, they weigh 30 pounds each.
Do you really wanna get bent over and spanked by a civic?

I really could care less how fast the car goes. I drive it 1-2x time/month anyway. They are not oem rims, they are the 10spoke from ecs tuning. I think they weigh 26lbs ea. My 17" factory rims weigh 23lbs so I don't think it will make a difference to me. If I was young, maybe I would care but right now I get lapped by old ladies in walkers! I don't care how long it takes me to get there, I just want to be comfortable and look good doing it! You feel me young pup?!! :slap:

just curious - is anyone running 18x8 on an XI and what size tires do you have? I am looking for something roughly the same height as my 205/50/17's. I live in upstate NY where there are potholes and I don't really want to worry about damaging the rims on low pro tire.

I was thinking 225/48/18's or 235/40/18's but I am really not sure.

Thanks

I'm running 18x8-1/2, with 235/40R18W Toyo Proxes 4 for summer.

Rick: Did you notice any difference in the ride (good or bad)? I am assuming no mods needed to be done to fit these tires on an XI since we have the extra room, correct? Thanks for responding.

Thie ride is a little more harsh than the 17" stockers. Anytime you decrease the height of the sidewall, you sacrifice some comfort.
Note that my suspension is not stock. I have Eibach springs and Koni shocks. I have a serious spinal condition and it doesn't bother me much-Bad bumps will alyways be bad.

Rick - I wanted the tires on put on there to have the same height on the sidewall as my prior tires to eliminate that. I have the 205/50/17's. Any idea what size tire will give me this? Sorry to hear about your condition, I wish you all the best.

Can't say exactly offhand. I once found a web tire size calculator, I can't remember where. Thanks for the kind thoughts.

No problem - I will check, thanks. Your condition is a lot more important than the size of my sidewalls!

18x8 on an Xi is fine. You must run tires that are the same overall outer diameter though. If not, your speedo will be off.

There is no such tire as a 225/48/18.

The correct tire sizes for an 18x8 rim are:
235/40R18
225/40R18
255/35R18
245/35R18

You cannot have an 18in rim and the same sidewall and still keep the speedo and all running the same. Your only choice for the sameish sidewall is to keep a 17in rim.

An xi with 18s will look like a rav4. You have to lower it a bit if you want to make it look right.

205/50/17 and 235/40/18 have roughly the same overall diameter and revs per mile.

jxs0402 11-17-2012 09:20 AM

Isn't there a way to recalibrate the computer system to match any size tire you put on your vehicle? what do these kids do that put 19" and 20" rims on these cars?
