The original size is 29.3 inches in diameter

The diameter shouldn't be a problem but how about the width. The width difference is 20 mm and half of that is 10 mm (thinking out loud) so 10 mm is .393 inches. Closer to the frame than a stock tire the way I measure it.

I have heard of people running 305/40/20 having problems rubbing the frame. This is a good topic I am sure you will get several replies by someone who has done this.

Maybe Steve will chime in.

Being just a tad shorter changed the speedo reading some.

Thank you,

40's are taller than 35's

The 305/315 is how wide, 35/40 the sidewall height

295 designates the tire width.

40 means the sidewall height is 40% of the tread width.

20 of course is the wheel size.

I have spent a lot of time looking at technical information on tire sites regarding overall diameter, revolution's per mile, tread & sidewall dimensions etc...to determine what would best fit on my Prowler when I need to again replace the tires.

My first choice, for myself on my car, would be to once again purchase the O.E. Replacement tire IF it were still available.
Yes I know the non runflat tire would provide a smoother ride but I feel safer in this car with the runflat.

What is amazing is that some manufacturers make a specific tire in only one size designed to fit one specific car and nothing else. I guess these other cars even though model specific, were made in much larger volumes each year than our car's entire production. It would be nice if more manufacturers would add our rear tire sizes to their productions that match the front they already produce,(or the other way around). Goodyear foe example produces both sizes for our car but not the same series or tread patterns which I feel to be important.

It seems that every time I find a tire I think might work for me, I can't find it again. Searching tire sites can be extremely frustrating and "Tiring" mostly because they don't seem to be easy to navigate for those of us trying to be creative at finding a solution to our needs. JMO

I am considering the following tire sets because they appear to be close enough in sizes to work acceptability regarding revolutions per mile, diameter, and width specifications:

Goodyear Eagle RSA (P295/40R20 & P205/50R17 or 215/45ZR17)

Goodyear Eagle LS-2 (275/45R20 & 225/45R17)

Goodyear Eagle Sport, All Season (255/45R20 & 225/45R17)

Pirelli P Zero Run Flat (295/45ZR20 & 225/45R17)

Pirelli P Zero Max Summer Performance (295/40R20 & 225/45R17)

Pirelli P Zero Rosso Max Summer Performance (295/40ZR20 & 205/50ZR17)

Continental Extreme Contact DWS 06 (295/40ZR20 & 225/45ZR17)
