Wheel Sets - Hub sizing
I purchased wrong Hub size wheel set, with rear width at 135M. My frame is 130M, can I force it in there or am I putting frame at risk?

Steel frame, yes, you could spread the rear triangle. Carbon or aluminum, no.

If you can send it back with free shipping, probably the best way to go. If you have to pay for shipping and a re-stocking…
Everything depends on the hub and how it was built to 135mm.
If the exact same hub (same flange-to-flange) is offered in a 130mm OLD, then you might be able to take the 5mm out and re-dish it. But how shallow the dish currently is on the DS is a big factor.
Best case would probably be 1mm DS and 4mm NDS and the DS dish is no worse than a typical 130mm wheel.
You will have to take enough measurements beforehand to know if it will work.

Edit added: And you only have to get close. Mfg sometimes make frames at 132.5mm so you can use a 130mm or 135mm. If you get the OLD between 131mm and 132mm, you are probably fine.

It would be good if we knew what wheelset you are talking about.

what wheel set? what frame?
BUT.... .the very fact that you need to ask implies DONT.
send it back -or- ask a lbs -or- upload some pics.
in general changing the rear spacing is a non-trivial skill that needs initial guidance.

What is the rear hub?
How is the rear axle built?
If the axle is threaded end to end, then often there is a series of spacers on the left side. Remove 5mm worth spacers, then either re-center the axle if you have fat dropouts (aluminum), or cut if narrow dropouts (steel). If you have loose ball bearings, you'll have to re-adjust the cones.
Technically your wheel should be redished by adjusting spokes to move the rim to the left about half the distance of the removed spacer (2.5mm). It is a bit of a fiddly job, but it can be done at home.
You can get advice for the update under the Mechanics section:
