I just bought some 2009 Zr1 replicas which are 17x8.5 and 18x9.5. I was wondering what is the fattest tire i can put on the back 18x9.5 and if it can be to low profile. I found some 295/30/18 but i don't know if that is to low profile and if a tire that wide would fit. Also and any recommendations on the front tire sizes?

Thanks for any help because i am a wheel and tire newbie

 

Do you have a 93? Might want to add a "signature" with basic info about your car - year, model, engine, trans and any major mods. That way people won't have to ask.

If it is a 4th Gen, it left the factory with either 26.1" (base V8) tires, or 25.7" tires (V8 with Z-rated option, WS6 or SS). You need to match the tire diameter to keep the speedometer accurate. Or you need to correct the speedo via a gear in the VSS (93 only) or programming the PCM (all other years).

A 295/30-18 is too small a diameter, at 25.0". You would be looking at a 275/35-18 (25.6") or a 285/35-18 (25.9"). You might consider a 295/35-18 at 26.1", but most tire manufacturers recommend at least a 10.0" wide wheel for that size.

 

I'm running 18x9.5 on all fours with 275/35-18. I wouldn't want anything lower profile and the width is perfect. Here's a pic for reference:

 

those wheels look damn good. ive been wantin 2 get bigger wheels 4 my 95 but haven't really found any i liked until i saw those. does it still have a comfortable ride w/that tire and wheel. if u dont mind me askin where did u get them from.

beast93 could u post some pics of yours also, id love 2 see what the new zr1s look like.

 

Nice

 

Thanks

Thanks, those are uncoated polished aluminum ZO6 wheels from AFS. I bought them with with tires mounted, balanced, and shipped for $1,200 or $1,300 off Ebay back in '03 or '04. They MUST be polished about once every 6 months or they turn yellowish and start to pit. They always look brand new after 4-6 hours of polishing. I honestly didn't notice any difference in ride quality other than the wider tires want to grab the ruts in the road.

And +1 for wanting to see pics of the ZR-1 replicas.

 

where did u get the zr1 replicas from?

Are you talking about these 2009 ZR1 wheels?

Mine are chrome 18" X 91/2", +56mm. offset with 285/35ZR18 tires.

 

Looks great The question is does it ride as good as it looks? Those are some pretty low profiles.

 

I think I'm definitely going to have to pick up a set of the new ZR1 wheels. Any pictures from farther away?

 

How about this?

Now those just have me sold on them. I'll have to find some that aren't chrome though.

So I bought 295/30/18 for the back and 245/35/17 for the fronts. Hopefully they will fit and if not its time for the bfh mod

 

They should "fit" because they are both smaller than the stock diameter tires. 25.0" in the back and 23.8" in the front (dangerously too small). The fender gap will be almost 1/2" larger in the back and 1" in the front.

Poor choices.
