Re: Stock Tire Size
wow I don't know how but I'm more confused . lol . 4" wide wheels ? is that a measurement for tread ? I'm still learning the vocabulary for this talk . and 4-1/2" ? I'm looking for a size that isn't going to rub , mainly because I had a blowout on the freeway and I think it's because of the rub it blew . or is it just because they were old tires . the other three seem to be solid but I know I need to get new so it doesn't happen again so easy. ooh and I don't have a spare , no rim . and that's another issue for me . I asked where I can get one for my car and the guy laughed and said maybe a junkyard ? are these rims hard to find now ? sorry for all these questions but I havnt had anyone to ask these questions about and I have alot more about my experience with this car the last 6 months . so I'll be quiet annoying for a bit .

Re: Stock Tire Size
Wheels arent that hard to come by. Post your location in your profile, there may be someone nearby that has a spare wheel.
If you post a picture of the blown tire, im pretty sure we could figure out whyit blew!

Re: Stock Tire Size
Maybe this will help, As mentioned previously he original tire size for the roadster was 5.60-14
The exact equivalency for this tire size in P-Metric would actually be 142/90R14 which obviously does not exist
However I have this spreadsheet which I built to use when looking for different size tires . starting from OEM here are the replacements and their differences ,

Re: Stock Tire Size
yes it helped . so on the offset . what's a perfect and what's the other I read back here . ? because I have a set of 185 and my speedometer is 10mph off on freeway and barely quickrubs sometimes . so I'm wondering if those are as good as that size would get . oh and my area is Pismo Beach . I've heard there's another guy with a 2000 around here . yellow .

Re: Stock Tire Size
Do you notice any issues with your speedometer with these tires? I see the diameter is 25.1 inches, versus the 24.5 for original (as I am told).
yes I do . 10mph off . it runs too slow .

Re: Stock Tire Size
195/75/14 is HUGE! It's almost a full 1" larger than stock. Not sure if you can tell but it looks like it is rubbing badly on your back tires. You can see body-color paint on the new sidewalls:

Your blowout, was it front or back tire? Could be from being old. Looks like the sidewall just gave.
