I am looking to get a set of 16" Enkei PKR wheels (7" width, +42 offset, 4x100/4x114.3) with Kumho Ectsa AST tires (205/50-R16 all-seasons). Wheels are 16x7.

Will this fit a 94 honda civic ex coupe without rubbing or potential issues?

 

Depends on how low your is most likely. I'd imagine that's a tad bit over ideal but probably doable if the car isn't slammed. I personally have 205/45R16 myself and the car is lowered 2.5 inches without any rubbing (+38 I think for offset).

 

205/45/16 is same as stock in height. 205/40/17 is same too. Your speedo will be be off by a little. But will fit if stock height.

 

What does it do to the speedo?

If I decide to lower later, can I keep the rims and change the tires to stock height 205/45/16?

 

205/50/16 is tall. Off the top of my head...its .75" taller than a stock 195/55/15.

You may get some inner fender rub on turns. You may get some rub on bumps if your car is lowered.

205/45/16 is like .25" shorter than stock.
215/45/16 is like .25" taller than stock.

Those are the two "acceptable" 16" sizes.

 

yes it'll fit. nothing will happen unless you have aftermarket suspension components. if so, you will have to adjust as needed to keep your tires from rubbing the fenders.
