I have a set of steelies that I wanted to mount some tires on because I just sold the rims off my car so I need something asap. Problem is I noticed the steelies are slightly different size, will this matter at all? 2 of them are 14x6 and the other 2 are 14x6.5. Also the center bores are slightly different (2.25" on the 14x6 and 2.5" on the 14x6.5).

I want to mount 195/60R14's on them, so they will all have the same tire on them. Will the rims being slightly different sizes be okay? If so, does it matter which ones I should put in front and which ones for the rear? Also, is a 195 tire wide enough for a 6.5" rim? I think the stockers are only 5.5".

 

I assume from your username that this is on a '92-95 Accord LX Coupe, correct?

The 1995 Accord LX Coupe came with 185/70-14 tires mounted on 14x5 rims. 195/60-14 tires are MUCH too small in diameter for that car, over 4 percent smaller in diameter, and that's a HUGE difference. Those are Integra size tires, much too small for your Accord. You can use 195/65-14 tires on your car, which is close to the stock diameter.

The stock size, 185/70-14, shouldn't be mounted on 14x6.5 rims, but you can mount 195/65-14 tires on both 14x6 and 14x6.5, no problem.

The '92-95 Accord came with a 64.1 mm center bore, which equals 2.52 inches. The wheels with the 2.25 inch center bore definitely won't fit on your car unless you bore them out. The ones with the 2.5 inch center bore probably will fit (and they may actually be 64.1 mm, if you're saying they're 2.5 inches based on measuring them with a ruler or tape measure).

All of these problems are why it's so much easier to get a matching set of rims that were designed for your specific car...

 

Sorry I didn't mention this in my original post but the rims are not for my accord. They are for my DA Integra.

 

Aha! Then 195/60-14 should be fine. And 195/60-14 can be mounted on rims 5.5-7.0 inches wide, so either wheel width, 14x6 or 14x6.5, should be fine.

All four-lug Integras came with center bores of 56.1 mm = 2.21 inches. So the wheels with 2.25" center bores should work fine. The ones with 2.5" center bores can be mounted, although there's a possibility you may run into vibration problems, unless you use hubcentric rings; without hubcentric rings, I'd suggest mounting them on the rear axle, not the front.

Bottom line, though, go ahead and slap 'em on...
