Wheel and Tyre Upgrade

by Bill Mon Oct 17, 2022 4:31 pm

I would like to upgrade my 15" alloys and tyres on my 2017 Symbol with 16" ones. As a non technical person is this a relatively simple upgrade or are there any issues to look out for ?

Can anybody recommend companies that sells complete wheel and tyre combinations. I am based in Norfolk.

Many thanks. Bill

When I looked into it last year I decided against it in the end because there were a few issues. Getting tyres with the same circumference was tricky. Theoretically increasing the diameter by an inch and reducing the profile could lead to a similar circumference, but I couldn't find a size that was all that close. This is important because otherwise the speedometer reading is affected. The other issue with Peugeots is that I think the vans supplied with 16" wheels have different spacing between the bolts to the 15" wheels. So you would have to be sure that you were buying 16" wheels with the correct spacing to suit a van originally fitted with 15" wheels.

In the end I just changed the tyres to CrossClimates which were available in the 15" correct size and a great improvement in ride, noise levels and grip compared to the original van tyres. Although I admit the 16" wheels would have looked much better. The 15" wheels do look too small for the wheel arches.

My Sussex (Marquis Warwick) has 15" wheels with original size tyres and according to my sat nav my speedo is extremely accurate so I could never change to bigger wheels for fear of inaccurate readings causing speeding fines to drop through the letterbox.

I bought your original tyres and have been very pleased with them, having had Bridgestones on the van from new, so I found them as good as the originals, thank you

If you even think of changing wheel or tyre size check first with your insurer. I wanted to change the low profile tyres on my Prius for smaller rims with standard profile tyres, maintaining rolling radius. Insurer told me that they would refuse to insure the car after the change. I could understand their attitude if I was changing the other way, is normal to boy racer but was puzzled as I wanted to go the other way.

There are 2 different wheel stud holes gape as to the vehicle max weight as the brakes are different so only some of what has been said above is correct but a lot is not correct

glyne - What isn't correct? It all makes perfect sense to me.

What are you trying to achieve - replace the standard R15 wheel/tyre with a standard R16 wheel/tyre which will increase the tyre's circumference, or, replace the R15 rim with a R16 rim but with a low profile tyre that won't change the tyre's circumference which is common with cars?

Can I just ask Bill the OP why he wishes to do this?
Genuine question as presumably there's some advantage in doing so.

GREAT to see someone that understands the difference
Now you do get 16 rims on the 5x118 but years ago the 16 rims all had the 5x130
When people put what they think will not help others but what Freelander has said is correct and thank you to him
When you have worked in the trade all my life see and understand the difference and when getting parts as to the vehicle spec have seen the difference here

I don't know what you are so upset about, it's pretty much exactly what I said in the first place.

Good grief. "People" only didn’t quote the PCD and offset because "people" couldn’t remember them off the top of their head having not “been in the trade”, and because the fitment is easily googleable. It’s not rocket science. Any reputable supplier will know which fitment is correct, buying secondhand from eBay would be a different story for the OP. So melodramatic. Are you this passive aggressive in real life?

With the poor words you are using and what you are saying clearly applies to yourself
All I have done is give the correct
information that it can be done and the difference
When doing up grades to the weight as to what a customer wants this is jobs I have done
When you Google as you say the information you read may not be correct and gets passed on again and again and will not help other people

I have found my notes from when I went into this in some detail whenever it was, 18 months ago? I spoke to Elite in Reading who supply a lot of these wheel/tyre upgrades. They told me there was no problem finding aftermarket 16” wheels which would fit the hubs and have sufficient strength, but to expect speedometer issues. So I spoke to Snow’s Peugeot who told me that Peugeot currently supply vans with three tyre sizes, all with a different circumference:

215/70R15

215/75R16 +6.7%
225/75R16 +8.9%

Fitting either of the 16” sizes would cause the speedometer to underread, because vans originally supplied with these sizes have the speedometer geared differently. As to whether this could be fixed, they said that it was done by a software factor setting, but that they could not (or perhaps would not) do it.

There are very few alternative size options when taking load rating into account.

Blimey…… time to relax everyone allthumbz

I’ve only just read this thread as I’m interested in why Bill (the OP) actually wanted to change from 15” to 16”?
I love a bigger wheel for aesthetic reasons but I’m more than happy with the look of 15” wheels on my Symbol of the same age.

by Caraman Thu Oct 20, 2022 8:12 pm

If the tyre on a R16 rim has a larger diameter i.e. not low profile, it should provide a less bumpy ride, better traction and sink into soft ground less. R16 tyres will also have a higher load index. Whether these improvements are sufficient to justify the expense of changing from R15 to R16 on a Symbol is another matter. R16 tyres will cost more to replace than R15s. I don't think aesthetics enters into it. We wait to find out from the OP what he is trying to achieve.

My 2010 van has 225/70x15 fitted and that's the size printed on the pressure sticker on door post, not mentioned in v8s post above.

What Peugeot currently fit or recommend may have changed since 2010. For my 2019 coachbulit they fitted 215/70/15 tyres. I believe the 215/70/15 tyre can be changed for a 225/70/15 tyre without changing the R15 rim. At least one member has done this to benefit from the 225 tyre's higher load index. A small change in circumference will have had some effect on the speedo etc. The wider tread reduces ground pressure and may improve traction but it increases cost.

Fitting 225 75 Michelin cross agilis crossclimates on our van has been the best change we have made. So much more confortable.
I did think about getting 16 inch wheels but decided to keep it looking original.[You must be registered and logged in to see this link.]

It seems like more of a minefield than expected. I did only ask about 2021 sizes, that’s true, and only Peugeot. I’m also not overly happy with the dealer’s unchangeable software explanation. It seemed a bit like being fobbed off at the time. Particularly as the speedometer drive is probably a cable, with a physical gear at the gearbox end. Perhaps that doesn’t rule it out, and in the past on a couple of cars I’ve changed the speedo drive at the gearbox end when changing rear axle ratios, for example. But I’d already decided to stay with the original wheels at that point.

The speedometer isn’t terribly accurate to start with, and that’s the biggest concern about changing wheel and tyre size. A GPS verified 70 mph currently requires the cruise control to be set to 73 mph. You wouldn’t want it to get much worse than that, especially in the other direction.
