16 x 7 inch is fine, Low profile tyres are legal as long as the load rating is at the minimum required or above, and your overall diameter (tyre + wheel) hasn't changed by more than 15mm.
If you have the correct profile on your rims currently and just simply want to "upgrade" to lower profile tyres, then yes it will be illegal as you'll most likely affect the overall diameter too much. As well as having your speedo innaccurate.

umm...

errr... wtf?!

The term "low profile tyres" is more or less used when you get bigger rims and don't want to change the rolling diameter of the wheel. So the lower the profile... usually the bigger the rim.

What choonga said.

Lower profile tyres on smaller rims can help handling slightly because theres less sidewall flex.

ive never seen anywhere that its illegal to have low profile tyres.

The screwed up problem I'm having is my current tyres are 16X7 with 21560R16 goodyear regatta's and the wheel at full lock, slightly touches the plastic in front of the auto and at the front in the mad guards.

I've been to 4 shops to see if I can find 16X6's so I can keep these wheels but cannot find any!

Went to a tyre shop and the guy said theres a set of 205's that are low-profile that will fix it.

Its either find 16X6's/ swap back to hubcaps/ or low profiles and sell these


suggestions????


The thing is I didnt think 7inch would be a hassle, its only scratch it slightly.

just get a lower profile tyre or one thats not a wide..

Ive got 225/35R20 and i have no trouble so getting a tyres thats a bit lower profile, maybe a 50 profile or something a little bit narrowier like the 205s and u should be fine.

You will not be able to get "low profile" tires on 16" rims. At least not what the normal person considers to be low profile. Low profile refers to how much rubber is seen when looking at a wheel side on. So if you get 2 wheels (tyre and rim) and one is 15" and the other is 19" then the 19" is lower profile.

I'm not exactly sure whats being asked here atm but if its of any assistance we've got lower profile tyres on our TR without changing the rolling diameter.

Stocks are 185/75 R14, ours are 215/65 R14, basically exactly the same rolling diameter (0.3% different I think). Does that help at all? :P

What a load of rubbish.
"Profile" refers to the height of the sidewall expressed as a percentage of the width of the tyre. It is known as the Aspect Ratio.
Number 60 or lower is considered low profile. Tyres with profile below 50 are considered ultra low profile. Diameter of the rim is irrelevant when talking about profile of the tyre

And to answer your problem it's the offset of your rims causing the scrubbing and not the tyres. I have 17x7s with 235/45 tyres and they don't scrub on full lock.

Thats what I'm worried about, but I dont wanna fork out more money


Is is possible to leave the two on the back as is and actually have steelies on the front?

Even if the inch's are different? Otherwise im in a painful position

Cut the plastic on the guards where it hits? Mine seem to have that part cut out of them before I got the car...

I know what profile refers to and what not. But sidewalls would be the same height when comparing 185/60r15s and 205/50r15 despite the "profile" (technical meaning used here) being lower. I am simply refering to what most people refer to as "low profile" being the less sidewall the lower the profile.

On another note: Narrower tyres means that you need to get higher profile tyres so the rolling diameter changes as little as possible.

done it, though it has some light scratch marks hitting the transmission and the front plastic, had a look at it today.

Might have to go back to steelies all over.

If you want your car to look gross yeah. Only other option is to buy a cheap set of second hand rims that you like if you dont wanna fork out more money, may recoup costs by selling your 16s.

just change to a 215/55 tyre or even a 225/50. that will stop the tyre rubbing, as well as lower the car a bit, and make the mags look bigger, and make the car handle a bitter better as there won't be as much flex in the tyre.

infact even a 225/55 which i think is the stock tyre size of the 16" tyres from mitsubishi will drop about 6mm off the diameter of your tyre and help with the problem a bit.

Just need to know are 21560R16 Goodyears regatta's 95V on a 16X7inch rim legal on the
2nd gen TR's??

Upgraded from the normal hub-cap steelies.

My car dosent have a placard on it.


Need to know 100% so insurance covers it, because I've heard the wrong tyre/rim can cancel your insurance claim.

Rim sizes on TJ/KJ Verada 16x6, Sports 16x7, AWD 16x6. They all have the same tyre size which is 215/60/16 95H.
That is factory fitment so one can assume that is all legal.
I might be wrong on this but I believe that no TR model was fitted with 16 inch rims.
There is no obstacle to upgrade 205/65/15 to 215/60/16. You need to ring insurance and tell them about upgrade so they can record it on your policy.

You are quite correct, the TR started with a 14" Steel rim (185/75 R14 Rubber) and moved up to either 15" Steel or 15" Alloy rim's (205/65 R15). No model across the range came with 16" or larger wheels. 99% sure the TS was in the same boat.

it shouldn't be much of a problem. i know that in qld if a car came out with 205 wide tyres the widest you can legally run is about 265 (30% wider than standard) and diameter you can go as large as you want provided the overall diameter doesn't change by more than about 15mm and the tyres have the correct load rating.
