Morris Minor Wheels are a good looking tyres. Though, they are a bit fickle for making them fit on vehicles both older and newer, depending upon what you want to purchase. We look at the trials and tribulations of Morris Minor Wheels and how to negotiate the challenges to fit them successfully onto your vehicles. Depending upon your vehicle and the tyres you want, you may have to alter your plans a bit. The earlier Minors featured bolts and side-valve engines rather than wheel studs and do feature a stud hole pattern of the 4-stud and 100mm variety. All Morris Minors tyres that are 4-stud and 4-inch variety, post-51, are four wheel studs. They are 102 mm or 4 inches apart from one other.
SO what does that mean? Well for those with the new sizing, which is common in modern vehicles, you can only fit mag wheels that are made for modern Japanese cars. You can fit the pre-51 Minor, though not on your Series II/1000 Minor. The earlier Morris Marina includes the same stud pattern as was featured on the post-Series MM Minor, which was also on the Vauxhall Viva.
To fit the mag wheels onto your Minor and have an early Series MM model, your choice of mag wheel styles is significant. The modern small Japanese cars use four wheel studs are using the 100mm sizing of the new Minors.
Do keep in mind that the majority of Japanese cars are front-wheel-drive and carry a different offset to the wheel than is desirable for a rear-wheel-drive car such as the Minor. The offset is the distance from the surface, where bolts and brake drum and disc meet, to the outer wheel edge. The front-wheel-drive offset is geared toward the inside edge when bolted onto the car. The wheel’s inner edge is oriented toward the car’s centre in comparison to rear-wheel drive vehicles.
To choose mag wheels for your Minor to try out the wheel and tyre prior to making a purchase. The problems arise in the areas of suspension for the kingpin at the front and inner wheel arch near the rear. Ensure a minimum of 5mm to 10mm clearance between the tyre and the closest non-rotating object. To clarify, this is while the wheel is sitting on the ground. You may be able to fit spacer plates on the distant brake drum though the excess load on the wheel studs and bearings is undesirable.
Again, the Series MM Minor’s wheel stud pattern is like any modern Japanese cars. Wheel choices are much wider. Later Minors pose a greater problem because the standard rims require you use inner tubes with Minor steels. They are tubeless tyres. The following model Van rims are wider though you still have to follow this rule of thumb.
Always fit the inner tubes to the radial tyres on the standard Minor rims. Though, the problem is that the Viva wheel includes a smaller centre hole where the axle and hub cover plate pass. Unfortunately, that means that the Viva wheels are not an instant mate for the Minor. Instead, you have to widen the hole by 8mm in diameter. Hire this job out to an engineering shop to machine on a lathe. It ensures the operability and stability of the wheel.
The less reliable and less desirable method to widen the tyre’s centre hole is to drill it. You would draw a line, and drill holes around its circumference. With the help of a cutting file or a hacksaw, you would cut around the sound hole until you achieve the correct size, which is 4 mm around. To achieve the best balancing, make the hole as round as you can. It might be operable and work, but could be illegal within your country.
If you have gone to all that trouble to drill a hole, the wheel studs may be too short and there may be little to nothing to screw the wheel nuts onto. You will need to have at least 3/4″ or 20 mm available. Otherwise, you may need to find some longer wheel studs to put these into place.
The standard Minor rims do not naturally work with the modern tubeless tyres. They can be fitted to Minor wheels though it may cause the actual tire to peel right off of the rim, particularly when you are driving under hard cornering. In the case of tubeless tyres, that is an instant flattie. Not the ideal situation.
Minor’s standard rim requires a 5.20 x 14-inch cross-ply tyre, which are costly and hard to find any with them available. They are additionally not good at handling. Instead, trade these out for radial tyres of the following dimensions; 155/70×14, This gives the Minor a better ride, and handle better by resulting in a smoother ride. Standard Minor rims will work with a maximum tyre size such as 175×14, with 165×14 being more commonly found in non-metric lands of measurement. The later model can take the 185×14 tyre.
Fitting the Morris Minor tyres can involve some thought, drilling, and other conscious efforts and investments. The reason is that they can be tough to make fit, depending upon the type of tyres you are seeking for your vehicle. Of course, the vehicle has the final say on what will work for it and what will not fit into the game plan. Look at how you can make this fit work for your vehicle. Just keep in mind that a professional can get in the mix to drill holes that are even and create a more stable ride with a more accurate fit.
