Gen 2 snows/rims to Gen 4 Two?

The Outside Diameter of second gen 185/65R15 is somewhat less, compared to 3rd/4th gen 195/65R15, say 2% difference in rev's per mile.

Also, how old are those tires? There's a date code on the sidewall, will show week and year. Google for more detail. If they're approaching 10 years it's probably time to replace.

Good shape? How much tread depth? You can get a tire depth gauge for $2~4, check it. With snow tires, 6/32" is pretty much the cut-off.

As far as rim compatibility, try mounting them, give them a spin. I'd suspect they're ok. FWIW I'm using Corolla rims on our 3rd gen, completely compatible:

Corolla 15" black steel rims p/n: 42611-02471
With lug nuts p/n: 90942-01007 (utilitarian, open-ended, galvanized)

 

I’m looking at the same thing.

Stock 15” rims on gen2 are 6j x 15 ET45.
On gen4 the 15” rims are 6.5j x 15 ET40.

With 195/65r15 tires on both rims, the diameter matches, the inset is very close (gen2 wheels are 1 mm further from gen4 suspension). The outset is less (11.4mm further inside).

If your winter tires are 185/65r15 on rims matching the stock gen2 Prius, you’ll have the -2% circumference error as Mendel said.

I’m more wondering about the effect of moving the center of the tire 6mm inwards.

Cheers

 

I wouldn't worry about the 6mm difference in offset, as long as the rims clear the brake calipers/holders you're good to go.

 

Same bolt pattern, on my 17 prime the snows are wheels from my 06’, any why not 195/65 15 tires, your speedometer will be spot on.

 

Gen2 rims fit on Gen4, and they look good.

 

You'll forget it's even there, soon enough. Keep an eye on tire pressures.

 

Are these steel rims? Aftermarket (with larger centre hub openings, one-size-fits-all) or Toyota, say Corolla? I've used a 2" ABS cap on the latter.

 

It's an end cap for 2" ABS plumbing pipe line. Inside diameter of the pipe is 2", it has 3/16" walls so outside diameter is 2 3/8", and accordingly that's the inside diameter of the end cap (converts to 60.325 mm). This is slightly larger than the OD of the lip around the hub opening on a Corolla steel rim.

I've found by snipping a "rubber band" of a bicycle inner tube, pushing that onto the hub lip, and then pushing the ABS end cap onto that combo, it virtually seats (the front axle nut/bolt slightly bumps it), and stays on securely.

Without something on there, I found after a few winters the exposed hub was terribly rusted up looking.

My other ploy is put a drop of oil, as little as possible on each of the galvanized, open-end nuts I have, brush it around. Otherwise the stud tips rust up quickly. Chromed acorn nuts would be preferable, but I don't have those. Also, all the aftermarket acorn nuts seem way too tall, again, one-size-fits-all I guess.
