Not sure what you mean about all the same wheels? You can have different size/width wheels//tyres on the front and back, but I think they have to be
the same as each other on each axle, i.e. the 2 fronts have to be the same tyre size/rating as each other, and the 2 rears have to be the same as each
other.

taken from the IVA Manual
1. Each tyre must bear an ‘E‘ or ‘e’, DOT or JIS approval mark (see notes 1 and 2)
2. Each tyre must be manufactured so that it displays permanently the following service information
a. nominal size
b. construction type (e.g. radial, cross ply or bias belt)
3. Each tyre must be manufactured so that it displays permanently the following service information markings
a. load capacity
b. speed capability, or
c. is accompanied by documentation that provides this information.
4. All tyres on the same axle must have the same structure (e.g. bias-belted, crossply or radial)
a. nominal size
b. aspect ratio
5. Tyres must be of the correct structure, taking account of their
position on the vehicle and the vehicle axle configuration. (see note 3)
6. Each tyre must be of the correct nominal size for the wheel to which it is fitted.
7. Each tyre must have the adequate speed capability (speed rating) for the maximum design speed of the vehicle (see note 4 and Annex 1).
8. Each tyre must have the adequate load capacity for the axle to which it is fitted (see Annex 2 and 3) at the manufacturers stated
maximum permitted axle weight (as indicated by documentary evidence or manufacturers plate) or where this is not available at the at the calculated
maximum permitted axle weight. (for calculated axle weight see section 44). Note where both are available the higher value will be used.
9. Tyres must be fitted in accordance with the manufacturer’s instructions as indicated on the side wall of the tyre
10. The load capacity of the temporary-use spare unit must be at least equal to one half of the highest of the maximum axle loads of the vehicle.
11. For temporary-use spare a 80 km/h / 50mph maximum speed warning symbol / reference must be permanently displayed on the outer face of the wheel in
a prominent position (see note 6)
12. The grooves of the tread pattern must be, at least 1.6mm throughout a continuous band comprising of the centre ľ of the breadth of tread around
the outer circumference of the tyre. (see note 5)
Note 1: It is acceptable that tyres displaying a ‘VR’ or ‘ZR’ rating do not display an ‘E’ or ‘e’ marking.
Note 2: Where the level of performance or safety provided is in question,
the vehicle presenter must provide documentary evidence to demonstrate
that the tyre would meet requirements equivalent to those of an ‘E’ or ‘e’
marked tyre.
Note 3: A four-wheeled vehicle fitted with single wheels must not have:
• a crossply tyre or bias belted tyre fitted on the rear axle and a radial
tyre fitted on the front axle
• a crossply tyre fitted on the rear axle and a bias belted tyre fitted on
the front axle.
Any tyre structure mix between different axles is acceptable for vehicles that have:
• two axles and ‘twin’ wheels on the rear axle
• three axles, one steering and one driving
Note 4: Evidence of, or a written declaration of, the maximum design speed of the vehicle should be produced by the vehicle manufacturer/owner
Note 5: Tyre tread depths are only required to be checked (using the digital tyre depth gauge) when it is visually obvious that there is a concern
with
that tyre.
Note 6: Temporary-use spare this speed warning symbol / reference is only required for wheel and tyre combinations.

I SVAed with 3 tyres of one type and one of another. The guy mentioned it and I said they were the tyres the wheels came with. Once it was on the
road I was going to fit some nice tyres. I didn't mention it again.
