Hi all, quick question for those in the know! Will a set of 16inch genuine allows bolt straight on to my 2001 Octy 2.0? Standard tyre size is 195/65/15 I believe, and the new size would probably be 205/65/16. Thanks all!

It would be 215 55 16, and provided its 5x100 pcd and an offset of et 45 -35 it should be fine

205/55/16 isn't it?

Thanks for reply. I have no idea what you mean by pcd, but it is 5 stud....also not sure about the off set? I know the wheels came off an Octavia 1 though if that helps.....

Then they will fit no bother. Chris and my tyre sizes are about 2mm or less different on circumference, so either of these would be suitable

The normal tyre size on an Octy with 16s (Elegance, L&K and vRS estate) is 205/55R16.

Hi all and Merry Christmas! Got the wheels and tyres for £160 for a breaker's yard near me. They are 15s. Fit okay, although the front ones seemed tight as far as tightening them up went. The studs I used were from the aftermarket wheels I replaced, is this anything I should worry about? Thanks again!

If the wheels are OEM then they usually use a radius seat bolt. Sounds like you have put 60º tapered bolts in that are used on aftermarket wheels. Would change soon as.

Thanks, so I should get standard dealer bolts? Also, the rear wheels were fine, is this normal? Thanks

Your probs best checking local breakers first mate. You want m14x1.5 with a round seat instead of a conical seat. You can get them on ebay and places very cheap. Would also reccomend a dab of grease on each bolt if possible

Thanks. Seen some on eBay for about £17 new. Say the seat type is radius, is that the correct type? The listing says they fit standard and aftermarket alloys and steel wheels.

Do NOT grease your bolts.

They overtighten.

From Octavia 2 manual:

• Thewheelboltsmustbecleanandmustturneasily.However, they must never be treated with grease or oil.

If they are OEM alloys they should be a radius seat. Well the standard mk1 octavia VRS alloys are a radius seat.

As above post sounds like bolts dont need any grease. Ive always put a dab on to keep things from siezing up. Learned something myself :-)

I always copper grease mine, and use torque wrench. As the hubs/threads become dry and you end up with a screech whilst doing up or undoing. This is bad for the car,and can mess up your torque figures too.

Same here, Ive always done it. Maybe i will stick to greasing then lol. Wouldnt have thought it would harm....

No it will be fine.

Some mechanical engineers at Škoda thought it up one day "hey, let's tell people not to grease their wheel bolts for no good reason".

Do you ignore other advice in the owners manual too!?????

This is quite a good thread:

Ok mate point taken :-) will NOT grease my wheel nuts from now on. Appologies for suggesting to.

Been a mechanic for 15 years and odd dab of copper grease on hubs to stop wheels seizing onto hubs and odd dab on nuts aswell if there tight coming out, never had a problem plus it makes it come apart in future.

Just trying to promote good manufacturers advice.

Your choice but I don't grease mine.

Every mechanic I've ever used/spoke to puts a bit of copper slip in wheel nut threads. Interesting the manual says not too. I do mine with a torque wrench so I couldn't overtighten anyway without knowing.

Copper grease is fine! Had 10 cars and all copper greased! Zero issues

But you can overtighten...... Stretch the bolts. Take them past their elastic limit into the plastic zone.

Like I said, Young's modulus and all that *******s, Mu, friction and force.........

You're just lucky.

Put single grade oil in.

Drive on cross ply tyres.

........

Hmmm yes you can overtighten but that has jack all to do with copper grease

You have less friction with copper grease.

You apply same torque (force times distance).

Because you have less friction you can apply more force to the bolts.

You take bolts past their elastic limit (the point at which they return to their original length) and into their plastic (not plastic as in polyethylene, but plastic as in "plastic deformation" and they will not return to their original length.

Sorry to talk in simple language.

Then again i've seen some rusted up wheel bolts so doesnt that work in the opposite

More rust = more friction
