Question about rim sizing: 6jj vs 6j

[Eug]

I have an extra set of wheels. When my previous car got destroyed, it had my cheap steel winter rims on it. I still have the old alloy wheels in my shed.

My current 2012 Prius Plug-in takes these wheels:
195/65R15
6J
5-100
10 spoke

My previous 2004 Prius takes these wheels:
185/65R15
6JJ
5-100
5 spoke

Are these the same size rims? What's the difference between 6J and 6JJ? Note that I've seen a few sites claim the 2012 has 6JJ, but the official spec says 6J.

I want to know if I can use my old 2004 alloy rims for winter tires on my 2012.

195/65R15 < tire width/profile and diameter
5-100 < Bolt pattern

This is the only thing you care about

They will bolt on and not rub.

Your biggest fun, TPMS. Would guess you would need new sensors.

I'm looking up this online and the JJ seems to refer to the rim contour vs bead profile.

So I would imagine the JJ is not quite as important, but the 6 is.

I'll just have to buy the appropriate tires to fit. So I guess the question is if 195/65R15 6J tires will fit R15 6JJ rims, or if I have to specifically look for 6JJ tires.

They will bolt on and not rub.

No sensors on the 2004 Prius AFAIK. Ugh. Another expense.

BTW, my car doesn't come with a spare. Any recommendations for that goop sealant stuff that doesn't destroy the sensors? In lieu of a spare, the car came with tire sealant which I'm told is nasty to the TPMS sensors.

They will fit. 6 is the width so that is the same for both wheels.

 

[michal1980]

could be a different offset...

 

[Eug]

Offset is 45 mm I think for both.

http://www.wheel-size.com/size/toyota/prius/2012/

However, that latter link seems to indicate the Prius 2012 is 6.5Jx15 40 mm offset, although that is for a non-Plug-in Prius.

Man this is confusing.

 

[NutBucket]

.5" doesn't matter. They will fit.

 

[Eug]

I guess I'll have to get the shop to retrofit some TPMS sensors in the 2004 rims. What I should expect for sensor cost and installation, ballpark? I don't want to be taken to the cleaners on the sensors.

BTW, I came across another site that claims the 2004 has 6J, not 6JJ. I guess the rims may vary a bit.

Centre bore 54.1
12 x 1.50 lug
Offset 35-48 mm for 2012 and 35-45 mm for 2004.

So, pretty much identical.

I would just run your 2004 Wheels on your 2012 without TPMS. Why? Because in my experience your car will only work with one set of four TPMS sensors at a time.

Our dealer wants $80 to program new TMPS sensors on my Mom's 2014 Corolla. No way in hell we going to pay to have that done twice a year just so we can have TMPS working on the snow tires 3-4 months out of the year.

Unless you are made of money, I would just live with the TPMS light on the dashboard. The only caveat is that, according to my local tire guy, Federal Law prohibits tire shops from mounting TPMS-less wheels to cars that are TPMS enabled. So you will have to put the snow tires on yourself.

Save the $250-320 and go TPMS sensor-less for the snows.

 

[Eug]

I don't think they can mount them without TPMS sensors.

I just assumed the cars could recognize two sets of sensors, but you're right, the vast majority cannot. That's exceedingly moronic. WTF?

[edit]

I guess if you have your extra set of tires with the sensors installed, sitting on the floor of your garage, your car might sense those and incorrectly give you the warning light, if you have two sets of sensors that are recognized by the car.

The easy solution to this though is just to move the wheels somewhere else.

[/edit]

However, I see that some 3rd party tire installers will do the sensor ID reset for cheap, and there are even sensors that can use cloned IDs. I'll have to look into that with my local tire shops.

 

[Eug]

Just got a call from my local shop. They have sensors that can clone the OEM sensor IDs, so no problem there.

They said if I keep the old wheels some distance away from the car (in the shed and not next to the car) then the extra sensors won't be a problem).

That sounds like it should work just fine. If it were on my car, I would invest in a TPMS Reset Tool ... that way if I want to run tire pressures not what the car maker wanted, I can tell the TPMS what the correct pressure should be before it would set an alarm.

I'm curious, what would you set that to, and for what car?

My car doesn't turn on the TPMS light until the pressures hit the low to mid 20s, even though the recommended pressures are in the mid 30s. I would prefer the light come on when it's closer to 30. I'm currently running 40 psi though, just because that's what the tire shop set my new all seasons at and I like the feel.

 

[bruceb]

It all depends and on most cars I like to run about 3PSI higher than what factory suggests.
Most TPMS sensors do not care if you are above the factory suggested pressure, but some may be picky about it.

I was unaware that this is a thing.

 

[Eug]

Rims fit fine of course. Thanks guys.

The programmable cloned TPM sensors worked fine. Even with all 8 tires in the car the TPMS light stayed off, presumably because even the original Goodyear Eagle LS-2 all seasons I was hauling in the trunk were still fully inflated to 40 PSI. I asked them to inflate my new Michelin X-Ice i3 winter tires to 3 PSI above recommended, meaning 38 PSI front and 36 PSI back.

These programmable TPM sensors ran CAD$50 each, plus $58 labour for programming them (1/2 hour) for a total of CAD$258 (plus tax), or a little over US$180.

Because they have cloned IDs I won't have to reprogram everything when I put the all seasons back on in the spring.

 

[NutBucket]

Sounds like a good solution. I like it!
