will a 10x7 rim fit on a 89 subaru justy and how wide a tire will fit with out rubbing Hey guys, I think the answer to the original question is NO! The stock 12-inch wheel will clear the brakes just barely. I am pretty sure a 10-inch wheel will not fit over the brakes and if you have a GL car that came with the larger brakes, then even a stock 12-inch wheel won't fit.

I'm not having this talk any more. There's no way for you not to take offense for this so I won't bother sugar coating it. I think your talk about EJ20 engines going into Justys and putting 10" wheels onto your Justy etc. is the kind of ridiculous highschool kid talk that makes me want to start an invite-only forum just so that I don't have to hear the next three dozen brand-new-members ask the same tired questions pertaining to projects that they'll never even start. Merry dead baby jesus day

i asked a couple simple questions and it pisses you off im sorry as in another post it's getting harder to find anyone who carries 12" tires where i live most people are riding on 16's or better and it takes at least 3 weeks for the "tire place" to get them in stock the reason i asked about golfcart rims/tires is cus i can get them for about $22 a peice and dont have to pay for shipping and they are highway rated Well with tires that short you won't have to worry about being highway rated because you won't be going on the highway. Check it out: a 145/80R12 is approximately 21.2" tall. On a stock tire you'll turn about 3400RPM to go 60MPH. A 205/30R12 would come out to barely 16.9" tall That's 4.3" shorter. Figure 4300RPM to go 60MPH. With revs like that you'll have to take surface streets or hope to god your engine lasts. Don't believe my math on the wheels? Check it; - 12" wheel = 305mm
- 205/30R12 means sidewall is 30% of tread. 205 X 0.3 = 61.5mm
- 61.5 X 2 = 123. 123 + 305 = 428mm. 428mm = 16.85-inches

ok, i'll bite: math is helpful, honestly! small wheel vs big wheel: a wheel with a smaller diameter also has a smaller circumference (since it's calculated via: 2*pi*r or pi*d where d is the diameter and r is the radius) meaning one turn of the wheel will cover LESS distance than a single rotation of a larger diameter wheel so to get as far you need to turn the smaller wheel MORE times than the larger wheel since speed is distance over time to go the same speed the smaller tire has to spin more than the larger tire to spin the tire more you have to run the motor faster -> put smaller tires on your car you have to run the RPMS higher to keep the same speed you are confusing the energy needed to move the vehicle vs the number of times the wheel has to turn in a given time in order to go a certain speed here is some homework: go borrow a 10-speed (or 21 speed or whatever) bicycle and try a few different gears while thinking about the RPMS of the motor (how many times you are pedaling per minute) vs the speed of the bike. question: which is the correct analogy a) putting the chain on a smaller gear on the rear wheel is the equivalent to running a smaller rear wheel or b) putting the chain on a smaller gear on the front gears (the ones at the crank) is equivalent to running a smaller rear wheel looking forward to your answer henri

the larger the gear in the rear the faster you go the smaller the slower. now the oppsit is true for the front the larger the gear the slower the smaller the faster. due to the transfer of motion the smaller the crank gear the more energy is transfered from point a to point b now in reverse the larger the gear the less energy is transfered (this is assuning both gearing ratios are turned at the same rate) now going off this theory and results you are correct it will require more energy to propel the vehicle at the same rate (with the smaller wheel) thust requiring more fuel but why is it if i when you throw on a set of 37" mud tires it will render the same results? if im am incorrect please correct me. Wow. You flunked the question about gears and you're still focusing on "energy" and gas mileage when that's not even what Henri (and I) were talking about. We tried to explain that small wheels have to spin faster to go the same speed. Despite all of the ill speak, I am still here to try and help you. Study these animated images and see if it clears things up. Looking at the images above, I think it is easy to understand that if you use tires on your car that are 4 or 5 inches shorter than stock, you will have to spin your engine faster to go the same speed as before. When you put "37" mudders" on a truck, the engine turns less RPM to go the same speed as it did with stock 29" tires. however the engine is working harder because it has less leverage now and has more weight to turn, but that's a lesson for another day As far as the personal insults are concerned, I will deal with you privately about that.

is it just the US that seems to have problems getting tyres to fit the justy? i have no end of possibilities in the UK?

*Bangs head against wall* why oh why is it so difficult?! EDIT great explanation SJ Fraser, you crack me up, mate! Ah well, we all tried. He'll just have to blow up his engine or get sick of a 65MPH top speed I guess. As far as 12" tires go. yeah, I don't have any problem getting 12s myself here in the U.S. and as far as 13s go, the selection is actually really good. My only complaint is that there aren't enough choices in the 185/60R13 size. If I could get a 185/65R13 I would be in heaven, but those don't seem to exist in the U.S. Still though, tire selections are decent for the Justy IMO Wouldn't a Justy look like a clown car with 16.9" tires on it?

Must be a regional disparity in the US for availability of 12" tires. Here in northern New England and the rest of the snowbelt, these tires are getting extremely hard to find. After doing a pretty thorough internet search, looks like Tirerack is it for 12" tires. If they discontinue...I guess I'll be looking for some larger diameter wheels I'm pretty sure my Justy will still be around for at least 2 more tire changes...but I won't be using golf cart tires --Steve

Same here in the Mid-west, 12" is an exotic size now. Next will be the 13". IMO>RONAN

OK, last attempt I was just explaining this whole discussion to my girlfriend and she asked me: Did you try using the big dog-little dog approach to explain this? :DYes, that's it! OK, JG, listen up. When you see a man or woman walking two dogs on a leash, one big dog and one small dog. The three of them, man, big dog, small dog, are traveling the same speed. The human is taking the longest, slowest strides, the big dog is taking faster strides than the human but the small dog is taking really, really rapid short strides like a centipede on drugs. This is exactly what will happen with your car if you put tiny little clown tires on it. On the freeway the human will be the Toyota truck with 4.11 gears and 37" mudders turning 2500 RPM to go 65MPH. The big dog will be a stock Justy with 21.2-21.8" tires turning about 3500RPM to go 65MPH and the little chihuahua will be you on your 16.9" tires turning over 4300RPM to keep up.

as i said befor i understand why a 205/30-12 won't work but i generly don't drive at highway speeds I tend to only drive 10 miles a day so 145/0SR12 spending $38 a tire X 4 tires plus shipping is $184 where as 205/30-12 =$88 if i need to drive @ highway speeds i have a 97 chevy cavalier it has a set of 205/50-16 which are easy to find but tends to consume more fuel in short daily runs You know what, I hope you do put little clown car wheels & tires on your Justy. Would serve you right you cheeky little bastard. Too small to write me back in the P.M. I sent you. Typical twerp from Felony Flats.

I must be confused? I don't see the other guy's posts?
At least I admit ignorance about cars! The key difference between ignorance and stupidity is that ignorance is curable with knowledge.
I just wonder if this guy is confused about tire/rim size? Can someone repost this guy's comments? I'm so confused.

BLP, after some discourse, JG deleted all of his posts. I don't know if it is possible to retrieve all of the missing dialog but you're not missing much.
