I got white 99Honda Accord, few months ago I got 2 new front tire & that is the right size 205/65R15, Can I use 2 new new 205/55R16 for both rear, I bought if from my nephew for $175 for 2 coz still new from his totally wreck new Honda Civic(not sure what year I know it's like few months only). Would it be a big different if I used a different size. Most of the questions I have read is mostly the first 3# _ _ _ /_ _ R _ _.

The correct tires for all = 205/65R15 2 new in front

Can I use a different size? = 205/55R16 2 new for the rear if ok.

both tires on rear is worn out and now rear passenger tire is flat and the wheel/tire wont come off, even all log nuts is off, tried everything, but still won't come off, felt like is welded. Maybe I drove and didn't notice it's flat already... Not really sure....

1010tires.com has a tire size calculator, if you compared the two tires you'd get these results:

Stock Vehicle Tire Size:

Section Width       8.07 in
Rim Diameter        15.00 in
Rim Width Range     5.50 in - 7.50 in
Overall Diameter    25.49 in
Sidewall Height     5.25 in
Radius              12.75 in
Circumference       80.09 in
Revs per Mile       815.94 /ml
Actual Speed        60.00 mph
Speed Variance      [Reference]
Diameter Variance   [Reference]


Section Width       8.07 in
Rim Diameter        16.00 in
Rim Width Range     5.50 in - 7.50 in
Overall Diameter    24.88 in
Sidewall Height     4.44 in
Radius              12.44 in
Circumference       78.16 in
Revs per Mile       836.08 /ml
Speedometer Reading 63.67 mph (3.67 mph higher)
Speed Variance      2.47% too fast.
Diameter Variance   -2.41 %

Notice the overall diameter of the new tires is 24.88 in, 0.61 in smaller than the original tires, so for one mile the new tires will spin more times, throwing off the speedometer (it will read 63.67 mph when you're really going 60 mph).

But, since the tire's smaller it should not interfere with anything on the car, and the bigger rim won't hit anything on the inside either. If the diameter were larger, or the rim size smaller, you could have interference problems.

The site recommends staying within 3% of the original size, much larger tires could cause braking problems (a "longer lever" effect).

So, the new tires should fit ok.

I'd notice that the Sidewall Height of the old tires is 5.25 in, but the new ones are only 4.44 in, 0,81 in smaller, so a rougher ride is possible too.

About the rear wheel being "stuck", if there's really no lug nuts still holding it on, the rim's probably just rusted & stuck onto the hub, I'd try a hammer on the sidewall of the tire (inner or outer) to knock it loose, and the tire's being replaced anyway. A pry bar would be a last resort, it could be very easy to bend something important.

If you're re-using your nephew's rims too you'll also have to check the rim's bolt pattern and offset, I don't know the year of the Civic, but not every Honda from every year will have matching bolt patterns. Just check a web search, or it might be written on the rim.

You should probably phone some local scrapyards too, they often have used tires in good shape and you could get the right size. If you're in America I wouldn't expect a used tire & rim to cost $88 either, especially from a pick-your-part type place a tire & rim should cost a lot less. For example, Pick-n-Pull in Modesto, CA charges $17 or $19 for a 15" tire, plus $7.99 for a 5-lug steel rim or $11.99 for a 6-lug steel rim (or $20.99 if an aluminum rim). So you could pay $25/tire for the right size instead, if you don't mind walking around & taking them off yourself.
