Love big wheels. 29" is a game changer compared to 26".

The real reason why wheels have grown massively in recent years, azmazingly, is pedestrian impact legislation.

Impact legislation forces the bonnet line to be higher. The wheel arches then grow to avoid an awkward-looking expanse of bodywork above the front wheel, and the wheels then have to grow to fill the enormous arches.

it very much depends on your intended usage. 29" certainly has advantages over 26" in terms of rolling resistance and comfort on slightly rougher surfaces, however it comes at the expense of strength, weight and handling, which are all more important to me for my favoured uses, but I do concede that 29" has it's place.

I still maintain that 27.5 is an unnecessary marketing gimmick that has the disadvantages of both and the advantages of neither.

I hope we are both talking about the same types of wheels, and that PH will forgive the thread diversion

When specifying my new car I wanted to keep with the standard 19" wheels but with other options I wanted it put the car over the critical 50g/km for BIK tax to 51g/km. Added 20" wheels and it dropped to 49g/km.

I assume it must be due to the weight of wheel and tyre combo.

I've recently gone from 26" to 27.5", at first I thought the same, gimmick. To my surprise, I am enjoying them more.

My car is still rocking 15" and 16" wheels currently. The trend to up-size with low profile tyres is lost on me.

I'll concede my jump bike is better with 26". MTB though... 29" all the way. Never broken a 29 wheel yet and smashed plenty of 26ers in my time. I'm probably riding harder and faster than before too.

Makes sense ....

also allows for larger brake rotors to help stop cars that are now heavier (due to safety features added)

I’m not a fan.

My next daily will need to be an estate with 4WD, also with a bit of height. Most definitely NOT an SUV as there will be a lot of long distance work.

The A6 Allroad is an option and the trim with all the goodies, comes with alloys like this:



21” alloys on a 4WD estate designed for “Allroads”? Ridiculous.

Even the base model has 19’s.



As someone else has said, as cars have got bigger, so have the alloys needed to in order not to look silly. It’s an arms race.

I do like a bigger wheel, but they're a ball ache on a daily driver.

We've 18s on our M140i which is a good balance.

18s on our 330i also. I ran 17s on it for quite a while but the 18s look better IMHO.

19s on my Z4C. Overwheeled perhaps, but i think it carries the look off, and its a weekend car.

I changed from 17 to 16" diameter wheels on my XJ almost the moment I bought it.

Instant improvement in ride and refinement and the 17" wheels and tyres were sold for enough cash by somebody who'd obviously never driven a XJ on that size to cover the cost of new rubber on the 16" ones.

It's a win-win. smile

I've always liked bigger wheels for the way they look(fill the arches etc) and I have 19" on the M4/19" on the 370Z/20" on the GLC. However as I'm getting older(and a bit boring maybe) the ride on those wheels is starting to annoy me far more than it seemed to when I was a bit younger.

I feel like I want a nice barge now on small wheels and with air suspension! biggrin

Big wheels certainly look good, but I like to drive my cars, and smaller wheels handle and ride better. My last 4 cars;

330d - came on 18s, swapped to 17 rode better, handled better
530d - came on 19s, swapped to 18 rode better, handled better
535i - came on 20s, swapped to 18 rode way better, handled a bit better
GTi Performance - just acquired on 19s and waiting for shipping from Germany on a lighter set of 18s

All of the above improved (or will) the dynamics of the car and were broadly cost neutral once I'd eBay'ed the flashy big wheels.

It's looks vs performance. Simples.

I love the small wheels on my 530d, with the standard suspension its very comfy even with RFTs. It has the bigger 348mm discs on it and I really like how the caliper only just clears the wheel.

To look at yes, drive on, it's a no. My GTI has 18s and it's not bad but think it would feel better on 17s all round.

That's part of the reason why after considering the VAG options I ended up with a Volvo V60 Cross Country, available with 18" wheels.

Some cars with small sidewalls ride waaay better than other cars in their class with much taller sidewalls.

Sidewall height is only one indicator of ride quality.

The quality/calibration of engine/powertrain mounting has a much bigger influence on ride than switching from a typical 50 to 45 or 40 profile.

Tall sidewalls, often have horrible, undamped bouncing ride.... yuck...

My FK8 Type R comes with 20 inch wheels, and 30 profile tyres, I'm really not a fan of them. There's so little side wall, and the wheels are gloss black, the car looks under wheeled. I've purchased some 19 inch wheels, with a 35 profile. It should improve the looks, and the ride quality. I did consider 18s, but they really would look too small in the arches I think. I may loose some of the turn in, but the 20 inch wheels, and rubber bands may be good for the Nurbergring, but not for the luner surface like roads in Malvern!

I swapped the 19s on my Alpina for 16 inch steelies with winter tyres with massive sidewalls and it drove so much better. The ride quality was transformed too. I rarely used the stupid 19s after that.

I swapped the V12 in my Lamborghini for an i4 diesel with common rail and turbo and it drove so much better. The fuel economy was transformed too. I rarely used the stupid V12 after that.

It's gone completely mental and the 'bling' demand is partly to blame

I know cars are larger now and there is demand for bigger brakes but back in the day (early 90s), 15'' alloys were decent for a hot hatch. Now it's 19''

A high performance saloon/coupe like an M3 would be 16''/17'', now it's 19''/20''. i think even the BMW 850i (which is a huge car) only had 17''s.

Porsche 911 was 16'' now 21''

Keeps the wheel refurb guys in business! That's another thing hardly any deep dish wheels fitted as standard now.
