new wheel and tire issue!

[DriverzInc]

Wow,
If that happened to one of our customers, I would would send a call tag for the wheels, and turn around and send them the right stuff!

Since you are only running 7s front and 8s rear, I would look into the 225/50/17 for the front, and the 255/45/18 rear. This puts a 26" tall tire up front, and a 27" tall tire out back, and would give you the same amount of sidewall from front to rear. The 27" rear tire will fill up the wheel well nicely.

Curious, why did you not go with a 8 front and 9-9.5 rear wheel? We set up most of our stock track width first gens this way with a 245 wide front tire, and a 275 wide rear tire.... in this combo we run a 275/40/18 which is 26.8 tall (so you can see that 27" tall tire will work).

Hold on a second here. So, you're saying that you ordered a 225/45x17 for the front and they shipped you a 235/45x17 for the front? And then you say that these fronts look goofy with too much sidewall? Well, the shipper sent you the exact sidewall that you ordered(45). The shipper just sent you a slightly wider tire(235 instead of 225). I wouldn't think a 45 series front on a 17" rim would look 'out of wack' with an 18" rear rim running a 40 series tire. In fact, if I was going to run a 17" front and 18" rear, that's probably the exact series I would pick, or maybe a 50 series in front with a 45 series in back. I run an 18" 40 series tire in the front with a 19" 35 series in the back and most people agree that it looks good. If you run a larger diameter tired in the back, which you are, then there's definitely nothing wrong with have a slightly lower profile tire in the back. That evens out the actual overall diameter of the tires from front to back and helps to keep the back from looking 'jacked up'.

Also, a 17" front with an 18" in the back should still look pretty good if you get the tire widths right. Yes, an 18" front with a 19" back might look a little better(opinions vary), but it's more costly. An 18" front and 18" back would look good too.

If I was to question your selection, I would wonder why you chose such a narrow tire(235) for the back. If your front tire is 235 in width, then I would think the rear tire would look a little funny if it was also a 235 in width. I would go to a 265 or even a 275 in the rear if you can nail the backspacing just right. You would need a 9" to 9.5" rear width rim for that larger tire size.

Of course, feel free to browse all the cars here and check what tires and rims sizes they were using if you're wondering what other combinations look like. There are also quite a few threads on popular tire/wheel size combinations.

Good luck getting things sorted out.

^^^^^^^^^^^^the sidewall size/# is a ratio number that depends on the width of the tire ie:the 235 and 225 in this situation.
so a 45 on a 235 tire will be taller than a 45 on a 225 tire... not alot but there is a difference.

Thanks everyone. I think the final solution will be 18x8's with a 235 40 18 tire up front and 18x9.5's with a 275 35 18 out back. What do ya'll think?

255 45 18 WORKS GREAT ON THE REAR AND A 225 40 18 ON FRONT . IF YOU ARE RUNNING A 17 ON THE FRONT GO WITH A 225 45 17 .
