93 metro tire size

Hi Everyone,

I just bought a 93 geo metro (my first metro!). According to carfax it's a XFI...don't know if that matters. But what I need to find out is what size tire I should be running. I live up in northern Idaho and it came with studded winter tires and an extra set of rims. I wanted to find a good tire for upcoming trips to Oregon and California (and also for the summer months).

Any advice? I'd like to maximize MPG as I drive about 600 miles/week to commute to school.

Thanks so much!

Came with 145/80-12. They're hard to find, most guys are running 155/80-12, just a smidgen taller and wider, you'll never notice the difference.

Best advice is to make sure it isn't rotted out.

You drive 60 miles each way for school?

if you want to maximize MPG on the highway I would suggest switching to the 155 80 R13 tires off of a 95+ Metro. This will cut your effective gear ratio to more like a 3.54 and require you to either switch the driven gear for the speedometer ( easy) or to compensate mentally for the lower speedometer readings. You will either need the newer cars bigger wheel studs or larger lug nuts to safely do the swap.

155/80 R13 will give you a "3.79" aka XFi transmission ratio.

Thanks for the info. Yes, we did a complete check of the body. The engine was rebuild 20,000 miles ago. Drives great! I commute 3 days a week for grad school. 200 miles round trip. Not to bad though. Just a little rough in the winter.

Budget is tight so I'll look at getting the 12' tires that way I can use the second set of wheels I got with the car. Maybe get a full size spare while I'm at it.

Thanks for the info. I'm sure I'll be one here quite a bit as we are going to work to redo the interior bit by bit!

Take care,

Chris

Um, CB , he said he thinks it is already an XFI, switching to the taller tires would more likely give him the 3.54 Jim-Bob mentioned. I think. From your excellant thread http://geometroforum.com/topic/3548347/1/

72:19 = 3.789 (1995+ 1298cc & XFI/1.0L/3 cylinder)

Welcome to the forum, baker2121! :coffee

My '91 came with studded snow tires on it and no extra tires or wheels. :smackface

If you are looking for regular tires, I got my set at Les Schwab and I see a set at www.tirerack.com/ in Yokohama Y372s for $52, each plus shipping ($41 to central Idaho). :banghead
