Tires 225/45/15 or 225/50/15


Recommended Posts

So i've looked through like 30 pages of post your wheels thread and can't find the right picture. I would like to get new tires for my 240z, I have a set of 15x8 ROTA rkr  with 0 offset. 

I would like a set of Hankook RS4 but they are only available in 225/45/15. I'm not sure how that's going to look on the 240z. I don't want a big gap between the fender and tire. Can someone post a picture of 225/45/15s on an 8 inch rim? Please also mention any modification to the suspension. Thanks

Rim width doesn't really matter for determining the gap between the fender and tire unless you are referring to being really low. A picture on your part may be helpful to determine what you consider acceptable.

 

A 225/45/15 is a pretty small tire. I had the BFG Rival S and they were really small in diameter.  23 inches if I remember, the stock tire size is around 25. The 225/50/15 is 24 inches which I think is a nice middle ground and looks good.

I have a 240z and yes I am running the extreme BC coilover kit.

 

That is unfortunately the case I think hondas and miatas run that smaller tire size so we're kind of out of luck.

 

Here's the car with the 225/50/15 Kumho Ecstas.

Just fills out a lot better. The factory tire size is actually even bigger then the 225/50/15, that fills out the well even better, but almost looks like too much tire at that point.

They have a pretty bad contact patch though

What suspension mods do you have? I run a 16x8 and 225/50. I could have easily fit a bigger tire in the back but the front only had a pinky finger gap between spring perch and tire. This is with stock suspension with new struts and lowering springs. I had run into the same issue as you while researching a tire size. If you want to run a bigger tire then you are going to need to get aftermarket coilovers. If you don't want to do that then you can run the 225/50 but may have to trim the spring purch. Personally my car sits to high with lowering springs and will be going with adjustable coilovers all around so I can run bigger tires and get a better stance.

Here is the car in question. In the picture the car has 15x7 or 15x7.5 +5offset epsilon wheels. Rear tires are BFG G force sport 225/50/15 (NLA) and fronts are Dunlop Direzza II 205/50/15. Suspension is all stock. There is entirely too much wheel gap on the front, and the 225/45 have the same OD as the 205/50, so that basically answers my question. 

Also i no longer have these wheels, right now i have a set of Rota RKR 15x8 +0 offset wheels with el cheapo 215/60/15 tires. They fill out the wheel well great but the car sits like a 4x4. grr. In hindsight i should have went with 16" wheels way more tire options.

Jester, thank you for posting the pictures of your car. it doesn't look bad with the 225/45 but i will definitely need to do some suspension work to change the car's altitude to make it look decent.

To make it look decent I think you would have to drop about an inch or so more then I am at, and at that height I was high centering the floor on things. 

 

I get what you mean though the 215/60/15 make the car look like its on stilts. Probably why my set only has 1000 miles on it. I am definitely planning the move to 16's, not many more tire choices, but the extra rim diameter makes more tires look "right."

I'll be picking up my Toyo R888R's in 225/50r15 next Friday, and they are going on my 15x8 ET0 Volk TE37V wheels.  I'll post pics once mounted.  

I'm lowered about 1.5 to 2", I believe, on MSA blue springs.  My arches are completely stock.  Fingers crossed I don't run into any issues :)

auxilary, those tires are great, unfortunately they are discontinued and weren't replaced in that size. The only Yoko option right now is advan a048 but at 230/ tire it's a bit expensive

 

ryant67, I'm also interested in the the looks of your car with that set up. I was worried about the R888R in wet conditions.

Thanks! I've found that is the ideal ride height on that tire/wheel setup to service the car. 2 finger gap all around and a low pro jack barely slides under the crossmember/diff. I was tucking tire before and the crossmember was basically on the ground. Absolute pain to get the car in the air.

I'm somewhere in the same boat, I had to make my front chin removable after I stiffened it up as I couldn't slide my jack under it anymore. Definitely been looking at some more interesting options to lift the car. Been looking at custom jack points or onboard air/electric jacks. I wish they had jack points like an E36.

I am actually still on that set of tires. I drive it nearly every day but my commute to work and the grocery store isn't that far  ;). Weekend trips occasionally maybe a couple hundred miles each time. I figure I have ~6000 miles so far, maybe another 4-6k left on them. Not too much wet weather driving but I've noticed they aren't that great in the wet. With a 3.9 clsd rear end and close ratio 5 speed, triples and tight suspension I can easily kick out the rear in the rain. Overall I'm happy with the tires and can't wait to get the updated set.
